"Searching for electromagnetic counterparts to high-energy neutrinos"

The recent discovery of high-energy astrophysical neutrinos has opened a new window to the Universe.

In September 2017, the detection of a high-energy neutrino in coincidence with a flaring gamma-ray blazar revealed the first compelling high-energy neutrino source candidate. At the same time gamma-ray blazars are disfavored as the dominant neutrino source class.

Other plausible source candidates are tidal disruption events, low-luminosity gamma-ray bursts and supernovae. Combining neutrino data with electromagnetic measurements in a multi-messenger approach will increase the sensitivity to identify other neutrino sources and help to solve long-standing problems in astrophysics such as the origin of cosmic rays.

I will review the recent progress in neutrino multi-messenger astronomy and high-light the potential of the novel optical survey instrument Zwicky Transient Facility (ZTF) to probe various source classes as neutrino emitters.

About the speaker

Anna Franckowiak received her PhD in 2011 from University of Bonn on "Searching for high-energy neutrinos from supernovae with IceCube and an optical follow-up program". Then Anna moved on to KIPAC/SLAC, where she did a postdoc in the Fermi-LAT team and worked e.g. on the Fermi bubbles and searches for gamma-ray emission from interacting supernovae and Galactic novae. In 2015 Anna started a staff scientist position at DESY in Zeuthen, where she's leading a Helmholtz Young Investigator group since 2017.
