Seminar Björn Davidsson: The formation of comet nuclei

Monday 3 October 2016

For decades comet scientists have debated whether comet nuclei are primordial rubble piles, formed at their current sizes through gentle accretion in the Solar Nebula, or if they are collisional rubble piles formed in the aftermath of violent collisions between larger icy parent bodies.

Seminar Wenfei Yu: Dormant SMBHs and GR effects: relativistic line reverberation mapping in tidal disruption events

Friday 29 January 2016

When normal stars run close enough to previously dormant supermassive black holes (SMBHs) at the centres of normal galaxies, they would be entirely or partly disrupted due to the tidal force of the central SMBH, leading to the so-called tidal disruption events.

Seminar Aurore Mathieu: Multi-wavelength follow-up of ANTARES neutrino alerts

Thursday 21 January 2016

The ANTARES telescope is well-suited to detect neutrinos produced in astrophysical transient sources as it can observe a full hemisphere of the sky with a duty cycle close to unity. Potential neutrino sources are gamma-ray bursts, core-collapse supernovae and flaring active galactic nuclei. To enhance the sensitivity of ANTARES to such sources, a detection method based on follow-up observations from the neutrino direction has been developed.

Seminar Lili Yang: Multi-messenger study of the Fermi Bubbles

Thursday 21 January 2016

The Fermi Bubbles have been imaged in sub-TeV gamma rays at Fermi-LAT, and, if their origin is hadronic, they might have been seen with low statistics in ∼0.1−1 PeV neutrinos at IceCube. I discuss the detectability of these objects at the new High Altitude Water Cherenkov (HAWC).

Seminar Thorsten Glüsenkamp: Analysis of the cumulative neutrino flux from Fermi-2LAC blazars with 3 years of IceCube data

Tuesday 19 January 2016

This talk gives a brief overview over the current status of the TeV-PeV neutrino flux and then discusses an analysis that has searched for the cumulative flux contribution from a large population (~ 900 sources) of GeV emitting blazars.

Seminar Felicia Krauss: Bert, Ernie, and Big Bird: Blazars as possible sources of IceCube PeV neutrinos

Tuesday 19 January 2016

The IceCube Collaboration has published results on a neutrino flux significantly in excess of the atmospheric background. Due to low atmospheric background at PeV energies, the highest energy events are the most likely ones to be of extraterrestrial origin.
