The role of accretion efficiency, natal kicks, and angular momentum transport in the formation of the Gaia black holes

Michela Mapelli, Cecilia Sgalletta, Johanna Müller-Horn +5

Gaia has the potential to deliver several tens of new dormant black holes (BHs) with low-mass stellar companions (hereafter, Gaia BHs) in the upcoming fourth data release. Three Ga…

BE Lyncis is not a Black Hole Binary: Lessons From Gaia and Hipparcos Astrometry

Pranav Nagarajan, Kareem El-Badry, Thomas J. Maccarone +3

BE Lyncis (BE Lyn) is a well-studied high-amplitude Scuti variable star (HADS). Recently, Niu et al. (2026) analyzed a 39-year baseline of times of maximum light of BE Lyn, rep…

The physical properties of post-mass-transfer binaries

Rhys Seeburger, Hans-Walter Rix, Kareem El-Badry +4

Aims. We present and analyse the detailed physical properties of six binary stellar systems, originally proposed as possible star-black hole binaries on the basis of radial velocit…

A Spectroscopic Search for Dormant Black Holes in Low-Metallicity Binaries

Pranav Nagarajan, Kareem El-Badry, Henrique Reggiani +9

The discovery of the massive black hole (BH) system Gaia BH3 in pre-release Gaia DR4 data suggests that wide BH binaries with luminous companions may be significantly overrepresent…

Millions of Main-Sequence Binary Stars from Gaia BP/RP Spectra

Jiadong Li, Hans-Walter Rix, Yuan-Sen Ting +6

We present the main-sequence binary (MSMS) Catalog derived from Gaia Data Release 3 BP/RP (XP) spectra. Leveraging the vast sample of low-resolution Gaia XP spectra, we develop a f…

The Nineteenth Data Release of the Sloan Digital Sky Survey

SDSS Collaboration, Gautham Adamane Pallathadka, Mojgan Aghakhanloo +209

Mapping the local and distant Universe is key to our understanding of it. For decades, the Sloan Digital Sky Survey (SDSS) has made a concerted effort to map millions of celestial…
