The timetable is loosely arranged according to the subareas of RU-D. There are slots for both 30 min (25 + 5 ) and 20 min (15 +5) talks.

1. Galaxies in transition to extreme environments
2. Formation and evolution of galaxies at the peak epoch of cosmic star formation
3. The chemical and dynamical evolution of galaxies
4. Understanding the physics of star formation
5. Formation and characterization of planetary systems and their atmospheres
6. The Cosmological ORIGINS Simulation Project

 

NEW MPA building access rules and corona measures:

• Entry to the MPA building is only allowed for people who are either fully vaccinated against the corona virus, have recovered from a corona infection, or have tested negative against the corona virus in the last 24 hours (PCR or antigen corona test).
• Participants have to confirm compliance with the building access rule via signature upon arrival, and as external visitors they have to be prepared to prove their vaccination, test, or recovery status by showing the corresponding certificates. Please bring your digital vaccination, recovery or test certificate, otherwise you can only participate via Zoom.
• Mask wearing is strictly required in the seminar room if the 1.5 meter distance rule is not fulfilled or when not seated.
• The mask-wearing mandate and social distancing in the hallways of MPA, and the recommendation for frequent hand sanitation, stay in place.

6 Massive star explosions and large-scale galaxy dynamics

Abstract: Gamma Ray Bursts (GRBs), commonly associated with Broad-Line supernovae type Ic (SNe Ic-BL), and Super Luminous Supernovae (SLSNe) are the brightest astronomical phenomena in the Universe, located in hearts of star-forming regions. These violent explosions not only are valuable laboratories for extreme physical conditions, but also are powerful tracers of fundamental processes in galaxy formation and evolution. Although the link between GRBs/SLSNe and massive stars is well established, the physical properties of the stellar population that gives rise to these rare explosions and the interstellar medium conditions in which they form remain poorly constrained. Our recent studies indicate a possible link between rare galaxy dynamics and the formation of massive star progenitors of these violent events. If this be the case, the extreme conditions induced by galaxy dynamics (due to external/internal effects) could be the factors singling out the environment in which these bright transients form. The large-scale galaxy dynamics can be traced through the distribution and kinematics of neutral gas. I will describe our ongoing survey of neutral gas in z < 0.1 host galaxies, designed to investigate the structure of gas in the close environment of SNe Ic-BL / GRBs / SLSNe, and to explore the extreme conditions responsible for the formation of the progenitors of these explosions. I will in particular focus on our findings for the host galaxies of SN 1998bw / GRB 980425, SN 2017iuk / GRB 171205A, SLSN PTF10tpz, and AT2018cow, studied as a part of this survey, supporting the likely connection between massive star explosions and peculiar dynamics. Such a connection being commonplace will set these energetic transients as tracers of galaxies with extreme dynamics and also will help improve our understanding of the progenitor stars of these events.
