Feedback-driven bubbles reshape the interstellar medium and influence the progression of star formation on galactic scales.  Thanks to facilities including Gaia and JWST, we can now resolve the local environments of superbubbles in the Milky Way and...

Abstract: The Swampland Cobordism conjecture asserts that in quantum gravity, any spacetime can terminate, i.e., the cobordism group of quantum gravity is trivial. A striking consequence of this conjecture is that it predicts the existence of...

Each week, we hold a relatively informal seminar/discussion series with an emphasis on extra-galactic and large-scale structure astrophysics.

During Galread a leader/visitor presents a recent paper to the discussion group. The PDF of the paper is...

Abstract: The theory of compact-object birth and core-collapse supernovae is now entering a new and productive phase of rapid insight into themechanism and systematics of explosion. The panoramic perspective provided by the recent access to tens of...

Abstract: On April 10, 2019, the Event Horizon Telescope captured the world’s imagination with the first direct image of a black hole. LEO VLBI Pathfinder is a SmallSat mission led by Brown University which seeks to take the next leap: Capturing the...

Among many things, dark matter could be made of new fundamental or composite particles, which may feebly interact with nuclei or electrons (“baryons”), as well as with themselves. Cosmological observables are a promising avenue to test such...

Details: Cosmological observables, from the Lyman-alpha forest to the Milky Way substructure, offer unique avenues for probing dark matter and neutrino sectors. Moreover, they often reveal anomalies and tensions that could signal new physics. I will...
