    SMBHs in Milky Way Satellite Galaxies

    The case for a SMBH in Leo I is gaining steam, and a discussion of the implications of such discovery could be interesting for several aspects of astrophysics, including galaxy formation, evolution, and black hole seeding.

    Fast Blue Optical Transients

    A new class of transients - Fast Blue Optical Transients - has recently been discovered, with around 5 such objects observationally confirmed. As yet, there is no fully fleshed-out theoretical explanation for these objects. What are the host galaxies? The energetics? The time-scales? How can we move forward with the theory?

    The New Milky Way near the Sun

    Combinations of 3D dust maps of the ISM and 3D measurements of the motions of young stars have recently revealed two previously unseen phenomena: 1.) a gigantic undulation in the Local Arm of the Galaxy ("The Radcliffe Wave"); and 2.) a preponderance of SN-driven bubbles nearby, the largest of which (the "Local Bubble") is roughly centered on the current position of the Sun. Meanwhile, simulations of star-forming galaxies are becoming "nearly" good enough to search for simulated analogs to The...

    "Migration of Low-mass Planets in Dusty Protoplanetary Disks"

    Fast inward migration of planetary cores embedded in gaseous
    disks is a common problem in the current planet formation paradigm. Even
    though dust is ubiquitous in protoplanetary disks, its dynamical role in
    the migration history of planetary embryos has not been considered until
    recently. In this talk, I will show that the scattered pebble-flow
    induced by a low-mass planetary embryo leads to an asymmetric
    dust-density distribution that is able to exert a net torque. Building
    on the results or a...
