Gaia neutron stars: demographics, birth rates, and connections to other neutron star populations

Cheyanne Shariat, Natsuko Yamaguchi, Kareem El-Badry +1

Gaia DR3 revealed a new class of neutron stars (NSs) in au-scale orbits with solar-type companions. How these 'Gaia NSs' form remains unclear, and constraining their intrinsic popu…

COPAS: Compact Objects and the Physics of Accretion Survey I. Accreting Binaries with P < 83 Minutes

Wendy Mendoza, Liliana Rivera Sandoval, Jan Kára +9

We present the first results from the Compact Objects and the Physics of Accretion Survey (COPAS), a high-cadence photometric survey focused on the detection of accreting white dwa…

Galactic Science with Ultra-High Angular Resolution X-ray Imaging

Paul A. Draghis, Jeremy Hare, Mayura Balakrishnan +8

Milli- to micro-arcsecond X-ray imaging will open a new observational regime for Galactic astrophysics by resolving physical scales that are inaccessible to current X-ray observato…

A new likely pulsar binary in 47~Tucanae from continuum searches

Thomas J. Maccarone, Alessandro Paduano, Arash Bahramian +6

We present evidence that the X-ray source 47~Tuc~W41, long considered to be an X-ray source powered by coronal activity, is actually a redback pulsar binary. The source continually…

Galaxy Clusters Selected via the Sunyaev-Zel'dovich Effect in 5 year data from the SPT-3G Main Survey

L. E. Bleem, M. Klein, K. Kornoelje +148

We report a new galaxy cluster catalog, selected using the thermal Sunyaev-Zel'dovich (SZ) effect, from 5 years of observations of the SPT-3G Main field. Drawn from arcminute-resol…

The Lazuli Space Observatory: Opportunities for time-domain and multi-messenger astronomy

T. Wevers, T. J. Maccarone, A. Palmese +14

Advancing time-domain and multi-messenger astronomy requires a multi-wavelength network of observatories capable of rapidly discovering, classifying, and characterizing transient p…
