News about Einstein@Home searches for radio and gamma-ray pulsars

Dear Einstein@Home volunteers,

We'd like to update you about our searches for new neutron stars using data from radio telescopes and from the Fermi gamma-ray satellite. Thanks to you, Einstein@Home has already found 55 new radio pulsars and 39 new gamma-ray pulsars. With your continued support, we believe that many more will follow.

All Arecibo data analyzed

Almost fifteen years ago, Einstein@Home began to search data from the PALFA survey, carried out at the Arecibo Observatory. Since that time, more than 150,000 individual observations have been processed. Our “BRP4” search recently finished going through all of the PALFA data, and we are now post-processing those results.

Green Bank Telescope

BRP4 is currently searching data collected in 2017 from the Green Bank Telescope. We expect that the initial analysis will be completed within the next two months.

MeerKAT

MeerKAT is an exciting new radio telescope, located in South Africa, that can search the Southern sky with more sensitivity, and with higher resolution than ever before. This means that there is a lot of data to search! Currently, the GPU-accelerated “BRP7” search is processing data from the TRAPUM survey. We are almost finished hunting for “black-widow” binaries in the globular clusters Messier 22, Messier 28, and Terzan 5. These are dense, spherical conglomerations of stars that harbour many rapidly rotating pulsars, especially in binary systems. After that is finished, we will search the data again, this time for looking double neutron star binaries.

Post-processing of Arecibo data coming to Zooniverse

The Einstein@Home analysis of Arecibo data identified more than 50 billion candidates. We have sifted through these using new tools and algorithms, and have selected a few hundred thousand which are the most likely to be new pulsars. This is too many for our small group to examine, so we are setting up a Zooniverse project. As soon as that goes online, please help us to hunt through the diagnostic plots for the characteristic signs of a new pulsar!

Finding gamma-ray pulsars in Fermi LAT data

Part of the Einstein@Home computing power is used to search through data from the Large Area Telescope (LAT) onboard NASA's Fermi Gamma-ray Space Telescope. Our current “FGRP5” search targets dozens of point sources which appear to be isolated neutron stars but where no pulsations have (so far) been identified. In parallel, the “FGRPB1G” search hunts for gamma-ray pulsars in binary systems. Here, we collaborate with astronomers to find the most promising targets, and preliminary observations from optical telescopes inform the gamma-ray searches. A 2021 press release about an earlier discovery provides some background on how this works.

If you have any questions, please let us know by replying to this news item in our discussion forum.

Does that mean, that in about 2 months from now there won't be any data left for BRP4/BRP4G?

Does the fact that the Arecibo data set had been processed mean the Arecibo binaries will be retired from Einstein  tasks application group?

Currently we are processing

Currently we are processing the Green Bank Telescope (GBT) data in our BRP4 pipeline. I just put up a "progress counter" on the Server Status page, it indicates that the current chunk will last for about half a year. Following that we will certainly have come across quite a number of Arecibo beams that will need to be re-processed. I don't think that BRP4 will run out work at least this year with the data that we already have. And already for GBT we added a bit of flexibility that allows us to process data from more and different sources / telescopes.

Thanks for the update!!! I know Einstein@Home for years now, but only in 2022 i put some effort into it, trying to understand it better and optimize my hardware for it... its really cool to get an update like this, it really encourages me to learn more and try to bring more computation power to the project.

I had been running E@Home

I had been running E@Home continuously for 12 months 24 hrs /day, just running Intel and NVidia GPU and achieving RAC of >500,000 on one desktop. However, I realise that there is a significant cost for the power, so have stopped, for now.

It doesn't really matter. I personally only run the program when my computer is powered on and used for working on my jobs, and I think that's where volunteer computing really shines: you know you are doing science when you are working for other things.

Also to the news: nice job everyone!

And that is exactly how anyone who doesn't want to run a system devoted 24/7 to this hobby should probably do it.  Then it truly is "spare" CPU cycles that the e@h home webpage mentions.

So far, my electricity budget can afford to run 24/7.  Depending on the rate increases that could easily change.

I'm relatively new, but I have a machine I use as a remote desktop, so it has to be on all the time, so it seemed wasteful for me to NOT do this project. Thanks for the updates. Helps me feel connected to a part of a community. By the way, is there a list anywhere of participants, or a rough idea of how big EINSTEIN is?

There is some basic stats about participants and theirs computers fleet on the status page of the project: https://einsteinathome.org/server_status.php

Right not there are about ~18  thousand users with ~42  thousand  computers working on the project

Benjamin Knispel from the project outreach here: Yes, this is still the case. If a volunteer's computer has significantly contributed to any discovery, the project will provide framed certificates and ship them to the volunteers. Furthermore, the volunteers will be mentioned in the acknowledgments section of the scientific paper reporting the discovery (if they agree to this). Bruce Allen will reach out to those lucky volunteers via email, so make sure you keep the email address in your profile up to date, and don't discard these emails as spam :-)

Awesome! I'll keep my eyes peeled then, might want to mention when the email blast goes out somewhere so once it happens I'll know to no longer expect one.

Good Evening/Afternoon! I

Good Evening/Afternoon!

I am new here and new to this in general. My love of learning about the Universe led me to this place and immediately signed up to be a part of this. I have only been a member for a few days now and read through so much of the community content its great to see so many passionate and dedicated people!  

I do not have any formal degree or training, I just simply love learning about the universe. That being said I was wondering if anyone could help point me in the right direction to specifically learn more about the items i am looking at with this project. 

For example I was working one of the GUPPI tasks and watching the cool screen saver's going and noticed that one of them had two solid white bars in the Radio Power Spectrum maxed out, dropping to about half and then maxing out again over and over. I thought it was pretty cool but the DM was super low at 7.36 pc/cm3. So i wasn't sure if it was something to get excited about or not.  Also, is there some training or something on how to read the validated reports? I would love to know what i am looking at. 

I don't mind doing the work to learn if someone can help point me in the right direction I would be EXTREMLY grateful! Thank you!

Welcome aboard! What you have

Welcome aboard! What you have seen in the screen saver could have been a pulsar (known or unknown) or radio frequency interference from terrestrial sources. It is not possible to make that distinction by looking at the simplified display on the screen saver based on data at a single dispersion measure trial.

What exactly do you mean by “read the validated reports”? Are you referring to the result files generated by your computer for a given sky position and DM trial value?

 

Cheers

Benjamin

I run my machine 24/7 anyway, so I let the Boinc client run all the time too. My machine has 8 real cores and 8 hyperthreaded cores. I let the client use up to 12 cores. I have 128 GBytes of RAM. Also  a large L3 processor cache.

During the day, I run Thunderbird for e-mail, Firefox for web browsing GnuCash for money management, and other odds and ends. I also watch videos if I get bored. But those things fit in the other 4 cores with no trouble.

I have watched every episode

I have watched every episode of "How the Universe Works". I have always been fascinated by space, but was too dumb to do any formal schooling. Math was never my strong suit. I was just curious how much data and information was attributed to this show? I have never heard any mention of the Einstein@home or Universe@home during any of these episodes. Seems strange though.

Anyway, glad to be here and helping.

If arguing with someone and the argument degenerates to name calling; you have both lost the argument.
