Gaia Data Release 3 (13 June 2022) contains astrophysical parameters for up to 1.5 billion sources derived from the low resolution BP and RP prism spectra, the...
Automatic Unsupervised Classification of All Sloan Digital Sky Survey Data Release 7 Galaxy Spectra
Using the k-means cluster analysis algorithm, we carry out an unsupervised classification of all galaxy spectra in the seventh and final Sloan Digital Sky...
BASS. XXV. DR2 Broad-line-based Black Hole Mass Estimates and Biases from Obscuration
We present measurements of broad emission lines and virial estimates of supermassive black hole masses (M BH) for a large sample of ultrahard X-ray-selected...
Beyond traditional diagnostics: Identifying active galactic nuclei using spectral energy distribution fitting in DESI data
Aims. Active galactic nuclei (AGN) are typically identified through their distinctive X-ray or radio emissions, mid-infrared (MIR) colors, or emission lines...
BlackCAT: A catalogue of stellar-mass black holes in X-ray transients
Aims: During the last ~50 years, the population of black hole candidates in X-ray binaries has increased considerably, with 59 Galactic objects being detected...
Blind search for activity-sensitive lines in the near-infrared using HARPS and NIRPS observations of Proxima and Gl 581
Context. Stellar activity variability is one of the main obstacles to the detection of Earth-like planets using the radial velocity (RV) method. Aims. The aim...
