First Pre-peak Ultraviolet Spectrum of a Tidal Disruption Event: A Fast Outflow Revealed Prior to Maximum Light in TDE2025aarm

Erica Hammerstein, Ryan Chornock, Jean Somalwar +32

The tidal disruption and eventual accretion of a star by a massive black hole can lead to the launching of outflows and winds that encode important information about the tidal disr…

Black hole astrometric binaries in the Roman Galactic Bulge Time Domain Survey

Casey Y. Lam, Jessica R. Lu, Kareem El-Badry +6

The Nancy Grace Roman Space Telescope (Roman), NASA's next flagship mission, is currently scheduled to launch in August 2026. As part of its mission, Roman will conduct the Galacti…

Spectroscopic follow-up of compact object binary candidates from Gaia DR3: White dwarfs, neutron stars, black holes, and the parallax zeropoint

Kareem El-Badry, David W. Latham, Hans-Walter Rix +12

Astrometry and radial velocities (RVs) from Gaia DR3 yielded orbits for hundreds of thousands of binary systems, including several samples proposed to contain black holes (BHs), ne…

Lithium as a Signpost for Compact Object Binary Candidates in the LAMOST Medium Resolution Survey

Yang Shen, Joshua D. Simon, Kareem El-Badry +1

Binary systems with black hole or neutron star companions are often associated with lithium enhancement. Gaia NS1, a recently discovered neutron-star binary with a lithium-enhanced…

TOI-7169 b: A Hot Jupiter Transiting a Metal-Poor Star

Joshua D. Simon, Joseph E. Rodriguez, Jhon Yana Galarza +38

Most known planets are found around metal-rich host stars, which has made it difficult to determine whether a lower metallicity limit for planet formation exists and how the proper…

Radial Velocity Orbital Solutions for Candidate Black Hole and Neutron Star Binary Systems in the Gaia Data Release 3 Catalog

Joshua D. Simon, Casey Y. Lam, Kareem El-Badry +8

We present spectroscopic followup observations of binary systems from the Gaia Data Release 3 (DR3) binary catalog that were selected to have large enough mass functions for their…
