[Lofarpwg] LOFAR2.0 PSR/FRB/Fast Transients EoIs

[Aris Karastergiou]

Hi guys,

I am following this conversation with interest. I think the key will be in the details. For MeerKAT, we opted for a single long (to get enough single pulses) pass of 1000+ sources, which didn't take up that much time, followed by monthly monitoring of several hundred, with the minimum integration time that gives us good fidelity. The value of 8h per source can be debated.

The high-level arguments about the science you are putting forward are interesting, but ultimately the objectives of searching and timing are the same: to understand pulsars and where they sit in a variety of problems in physics. In my opinion therefore, these campaigns need to be optimized in a practical way, maximizing the return from each and helping each other's objectives.

Not particularly useful, but those are my thoughts anyway.

Cheers,
Aris

hi Joris and Cees,

I really  do not disagree with any of you and I see good reasons for both visions.
Science-wise I'm  more on Cees' (and my original) view (most science, with some notable
exceptions, is overlapping among monitoring and long tracks on known sources, although on different timescales),
while on the implementation plan, I'm much more inclined on Joris' view, especially since
doing 1000 sources  with the monitoring will be  practically very  hard if not impossible.

Maybe an intermediate option could be to ask for the Census-1000 pulsars as a "piggy
back" program for the survey EoI, while keeping the description of the related science
and motivations in the "monitoring" EoI.

Anyway, just a second order thing. What's important is to have that implemented somewhere.

Hi Cees,

Just to quickly point out that I don't think I agree.

I do agree that scientifically there is a match with some of the science goals of the monitoring campaign and those of the long-track census; but at the same time a major goal of pulsar surveys is exactly charting the population of source out there -- meaning that there is an excellent scientific match there as well.

Also, in terms of required observations, the survey and the long-track census are perfectly matched, whereas the difference with the monitoring campaign could not be larger.

So I personally very much think the long-track census would be a logical part of the survey EoI -- but not of the monitoring EoI.

Cheers,



Joris

Looking at the notes I took of both the searching and monitoring
discussions, the "1000 pulsar census with 8h per source" was mentioned
as part of the monitoring program. To me that seems the logical
location to add this; it is a bit different to the monitoring done for
timing, but it is a better match than searching.

Regards,
   Cees
