FRB emission mechanisms
Central seminar room, library building
Abstract: Fast radio bursts are recently discovered mysterious single pulses of radio emission coming from cosmological distances (~1 Gpc). Their short duration, ~ 1 ms, and large luminosity evidence for coherent emission. I am going to review the basic physics of coherent emission mechanisms presumably responsible for the FRBs. I discuss the curvature emission of "bunches", maser mechanisms and the direct production of radio waves by a reconnecting current sheet in highly magnetized plasma. The polarization of the outgoing emission will be also considered.

Three elephants in the gamma-ray sky
Central seminar room, library building
Abstract: There are three elephants in the gamma-ray sky, extended diffuse emission that is just too big to be ignored: the Galactic centre excess, the Fermi bubbles and Loop I. Yet, to varying degrees, these structures are often times glossed over, if not ignored altogether. Lately, observational evidence and theoretical arguments have connected the Galactic centre excess with the Fermi bubbles and the Fermi bubbles with Loop I. This goes to show that neither can be interpreted separately and implies the need for a global picture.
We will work our way from the inside out, starting with the Galactic centre excess and its relevance for dark matter indirect searches. Moving on to the Fermi bubbles, I will explain our recent numerical model that for the first time allows reproducing the observational data from radio waves to gamma-rays with confidence. Finally, I will discuss the large, prominent radio structure Loop I, our ignorance of its distance and how it can contaminate the CMB.
