hi team,

 

As we all know, O1Low and O1High are over.

With all computing power moved to FGRP5 and FGRPB1G, they will both also end in aprox two months. 

So I wonder: What is next? is there an "end" to the search? Once we have detected some grav waves, do we really need to continue, ad eternum?

What about BRP4? Its been some weeks appearing and disappearing from stats...

 

Happy new year :)

No they won't.  New data is continuing to be produced by the large area telescope (LAT) on the Fermi satellite so I don't think there's any likelihood of running out in the near future.  Also, as indicated by Bernd here, there should be a new GW run starting relatively soon.

EinsteinAtHome hasn't detected any GW yet.  We're not looking for the type of GW event that's been found so far.  EAH wasn't designed for that.  We are looking for continuous emissions from rapidly rotating massive objects like neutron stars.  To suggest there's nothing more to see or do, just do something else is a bit like suggesting that once Galilleo described saturn as having ears or handles, 400 years ago, that should have been the end of that :-).  Now, 400 years later, look at how much more we know about saturn.  Should we stop now??  The pursuit of knowledge and understanding of the universe around us is ongoing and never ending, hopefully :-).

BRP4 relies on a supply of data from Arecibo which was rather damaged by a hurricane.  I'm not sure where repairs are up to at the moment.

 

Cheers,

Thx for your reply.   Well,

Thx for your reply.

 

Well, in that case why FGRP5 and FGRPB1G, if you go to https://einsteinathome.org/server_status.php have X work units and we "approaching" to their end? We can see work generator for both being run but still remaining units / days are less and less.

Of course I may not undertsand how those projects work :) 

Is not that easy to know what exactly each application does...Is there a link for reading it?

 

Thx¡

It's just because the server status page only knows what it has already been told and it doesn't yet know about what will be added to the mix in the future - days, weeks, months.  Previously, various searches did tend to have a fixed size.  These days it seems to be more common, particularly for FGRP searches, to add more data to existing searches and 'extend' them that way.

The Cafe is not a good place to ask questions of a scientific or technical nature :-).  There are various threads in the Science Forum  (eg a 'Plans for the near future' thread) and other more technical forums which have given details about various searches being planned.  When a search is first started, there will be an announcement in Technical News which will quite often give basic details of what the search is designed to do, as well as details about the app itself.  From memory, things started in 2011 with a search called FGRP1.  I think there was quite a bit of information given about the new search and its purpose at that time.

A lot of information can be found with simple google searches on the internet at large.  It's quite interesting to read some of the stuff about the Fermi Mission itself and the Large Area Telescope that is detecting gamma-ray emissions.  EAH is able to access the data for its own purposes, quite independent of the reasons for designing the mission in the first place.

EAH is primarily interested in detecting continuous GW emissions. These are likely to come from compact massive objects like neutron stars.  If you can find such objects relatively 'nearby', a targeted search for GW from such a body might have a greater chance of success.  So, EAH uses some of the resources available to it to look for suitable neutron stars.  Initially lots of new radio-pulsars were found.  Now we are looking for pulsars emitting gamma-rays.

 

Cheers,
Gary.

Can you guys get data from the one in China that recently came on line? Data is data right? Splitting it into chunks our pc's can handle is the big deal? And then putting it all back together again afterwards of course.
