ALMA Reveals the Molecular Medium Fueling the Nearest Nuclear Starburst

Adam K. Leroy, Alberto D. Bolatto, Eve C. Ostriker +11

We use ALMA to derive the mass, length, and time scales associated with the nuclear starburst in NGC 253. This region forms ~2 M_sun/yr of stars and resembles other starbursts in s…

Why do galactic spins flip in the cosmic web? A Theory of Tidal Torques near saddles

Christophe Pichon, Sandrine Codis, Dmitry Pogosyan +3

Filaments of the cosmic web drive spin acquisition of disc galaxies. The point process of filament-type saddle represent best this environment and can be used to revisit the Tidal…

The X-ray Luminosity Functions of Field Low Mass X-ray Binaries in Early-Type Galaxies: Evidence for a Stellar Age Dependence

B. D Lehmer, M. Berkeley, A. Zezas +11

We present direct constraints on how the formation of low-mass X-ray binary (LMXB) populations in galactic fields depends on stellar age. In this pilot study, we utilize Chandra an…
