Tianlai Analysis Teleconference

US/Central

AGENDA

0) Introductions of new (or recent) students:

  • Samit  - grad student at IITI
  • Harsha -  grad student at IITI
  • Lily Robinthal (recent graduate from Evergreen State (Olympia, WA), now at UW
  • Yanlin Yu - recent graduate from UW

1) Sun removal paper submitted - congratulations to Anh and Santanu!

2) Status of low-z simulations paper - Olivier & Reza.   See Dec 22 Indico page for latest version.

3) TAC Hacksession at UW on Weds Jan 19.   John & Albert visiting in person.  All others are welcome to join through our usual Zoom call.

  • summary of hardware tests of correlator.  Tests on (both dish and) cylinder correlators? Jixia
  • low-z simulations - Olivier & Reza
  • correlated noise - presentation/discussion by John Podczerwinski/ David Kwak
  • WIYN survey -
    • analysis so far - John, Albert
    • verification of some redshifts with NED catalog - Lily
    • NCCS/GAIA cross-correlation - Olivier
    • plans for next observations - Greg, John
  • other....

4) Pulsar detections with Tianlai cylinder - Zijie Yu

  • detected 1st and 3d brightest pulsars in Northern Sky, but can't detect Crab pulsar.   Not sure why not.  Clearly detecting other signal from Crab. 
  • dispersion measures consistent with literature
  • looking just at XX polarization for now
  • Yichao - can you do a stacking analysis to improve SNR?   Fengquan - not yet;  limited by software
    • is pulsar data in standard format?
    • how are you doing the de-dispersion?
There are minutes attached to this event. Show them.
