[Triumf-darkmatter] Tomorrow's seminar

[Nirmal Raj]

Hello, all



   Our theory seminar at 1 pm tomorrow (see details below) will be presented by Deborah Good from UBC, who will tell us about the recent, exciting discovery of fast radio bursts (FRBs) at CHIME, including the second ever discovery of a "repeating" FRB. Deborah will arrive here just before the talk, but will stay around after, if we want to chat with her about her work.


  Please send this around to anyone that might be interested.


Cheers,

Nirmal


Early Science Results with CHIME/FRB


Abstract: Fast Radio Bursts (FRBs) are millisecond duration, extragalactic radio emissions, which are as yet poorly understood, partially because only a few dozen have been detected. The paucity of detections and incomplete localization information complicates our understanding of FRBs and their origins. The CHIME/Fast Radio Burst Project (CHIME/FRB) mitigates this problem by using the Canadian Hydrogen Intensity Mapping Experiment (CHIME) located at the Dominion Radio Astrophysical Observatory in British Columbia to search for FRBs continuously. CHIME is a novel transit telescope coupled to a powerful correlator, which allows it to observe the entire Northern sky in its frequency range (400-800 MHz) each day. Pre-commissioning calculations predicted CHIME/FRB could detect a few to several dozen FRBs per day. Here, we present the first 13 FRB detections from CHIME/FRB, including a second repeating FRB and for the first time, the detection of FRBs at frequencies as low as 400 MHz.
