This is a talk given at lunch time, usually in the conference room at noon.
Large reservoirs of cold (~ 10^4 K) gas exist out to and beyond the virial radius in the circumgalactic medium (CGM) of all types of galaxies.
The gaseous interfaces between galactic disks and the circumgalactic medium are critical boundaries in the baryon cycle. These interfaces are imprinted with structural, chemical, and kinematic clues about the processes driving galaxy growth and evolution across cosmic time.
Unbiased all-sky surveys such as the Zwicky Transient Facility (ZTF) or the Pan-STARRS Survey for Transients (PSST) have opened up the door for the discovery of new and exciting types of transients.
Far-infrared (FIR) and submillimeter (submm) lines emitted from the interstellar medium (ISM) not only reflect the ISM physical properties that are correlated with the star formation (SF) process, but also trace the underlying density distribution and promise cosmological studies.
The mechanism powering core-collapse supernovae remains uncertain. I will discuss aspects of the critical condition for explosion, focusing on the model problem of spherical accretion onto a standing accretion shock.
Deep surveys have allowed us to chart the evolution of galaxies from billions of years ago through to the present day with unprecedented precision.
The Large Magellanic Cloud (LMC), the most massive satellite of the Milky Way (MW), is perturbing the dynamics and equilibrium of the MW.
Similarly to stars, planets also lose mass with time, even our own Earth. In particular, hot extrasolar planets orbiting close to their host stars are subject to large mass loss rates due to heating by high-energy irradiation and subsequent atmospheric escape.
