Gaia Data Release 3 provides novel flux-calibrated low-resolution spectrophotometry for≃
220 million sources in the wavelength range 330 nm≤ λ≤ 1050 nm (XP spectra). Synthetic …

Context. Gaia DR3 contains 1.8 billion sources with G-band photometry, 1.5 billion of which
with G BP and G RP photometry, complemented by positions on the sky, parallax, and …

Context. RR Lyrae stars are excellent tracers of the oldest stars (ages≳ 9–10 Gyr) and
standard candles for measuring the distance to stellar systems that are mainly composed of …

We present the first version of the Automatic Learning for the Rapid Classification of Events
(ALeRCE) broker light curve classifier. ALeRCE is currently processing the Zwicky Transient …

We report the discovery of a candidate binary system consisting of a black hole (BH) and a
red giant branch star in Gaia DR3. This binary system was discovered from 64,108 binary …

ABSTRACT The All-Sky Automated Survey for Supernovae (ASAS-SN) is the first optical
survey to monitor the entire sky, currently with a cadence of≲ 24 h down to g≲ 18.5 mag …

Many problems in contemporary astrophysics—from understanding the formation of black
holes to untangling the chemical evolution of galaxies—rely on knowledge about binary …

Context. Map** the Galactic spiral structure is a difficult task since the Sun is located in the
Galactic plane and because of dust extinction. For these reasons, molecular masers in radio …

We present the results of a multicomponent kinematic model of a large sample of RR Lyrae
detected by Gaia. By imposing a fourfold symmetry and employing Gaia proper motions, we …

The number of known periodic variables has grown rapidly in recent years. Thanks to its
large field of view and faint limiting magnitude, the Zwicky Transient Facility (ZTF) offers a …
