Speakers: Dr Shawn Dubey Detecting the redshifted 21-cm signal from the early universe requires separating an extremely faint cosmological signal from bright foreground emission and terrestrial radio-frequency interference (RFI), but flagging RFI is a big challenge. I will describe our use of weak supervision, a method that combines multiple imperfect flaggers to construct training labels ... Read more

1 event,Speakers: Peter Sorensen (Lawrence Berkeley National Laboratory) I will discuss recent results from PandaX, XENONnT and LZ, with an emphasis on the effect of instrumental backgrounds on the recent physics searches. I will then discuss recent results from the TESSERACT Collaboration, again emphasizing the effect of instrumental backgrounds and the so-called low-energy excess (LEE). I ... Read more |

1 event,Speakers: Tongyan Lin (University of California, San Diego) Stellar streams are a promising way to probe the gravitational effects of low-mass dark matter (DM) subhalos. In recent years, there has been a remarkable explosion in the number of stellar streams detected in the Milky Way, and hundreds more may be discovered with future surveys such ... Read more |
