SUMMARY:Chasing ghost particles: searching for neutrinos from high-ene
 rgy sources in real time\, Outreach\, Jessie Thwaites\, UW–Madison P
 hysics / WIPAC
DESCRIPTION:Neutrinos are tiny\, nearly massless particles that intera
 ct very rarely. Because of this\, astrophysical neutrinos can travel v
 ery far\, all the way to the South Pole\, carrying information directl
 y from their sources. The IceCube Neutrino Observatory has detected th
 ese astrophysical neutrinos\, but only a few sources have been identif
 ied thus far. We search for these neutrinos from transient sources –
  sources that vary in their brightness over time\, such as gamma-ray b
 ursts (GRBs)\, supernovae\, novae\, or mergers of compact objects. The
 se sources often have very energetic processes happening inside them t
 o accelerate particles and produce these neutrinos. By searching for t
 hese transient sources as they’re happening (in real time)\, we can 
 inform follow-up by other observatories also searching for them\, and 
 better understand the nature of some of the highest energy phenomena i
 n our universe.<br>\n<br>\nJessie Thwaites is a 4th year graduate stud
 ent in the UW—Madison Physics department\, working with Justin Vande
 nbroucke on the IceCube Neutrino Observatory. Their research focuses o
 n searching for high energy astrophysical sources of neutrinos from tr
 ansient sources\, in both real time and archival data. In addition to 
 research\, Jessie writes for Astrobites\, a daily science communicatio
 n blog that summarizes astronomy or astrophysics papers into bite-size
 d pieces for the public. Outside of physics\, Jessie plays horn and en
 joys hanging out with their cat\, Ryan.<br>\n<br>\nThis meeting will t
 ake place in-person at our usual Space Place classroom location. It wi
 ll also be streamed live to our YouTube channel at https://www.youtube
