We present a critical review of the determination of fundamental parameters of white dwarfs
discovered by the Gaia mission. We first reinterpret color–magnitude and color–color …

Euclid is a mission of the European Space Agency that is designed to constrain the
properties of dark energy and gravity via weak gravitational lensing and galaxy clustering. It …

Pan-STARRS1 has carried out a set of distinct synoptic imaging sky surveys including the
$3\pi $ Steradian Survey and the Medium Deep Survey in 5 bands ($ grizy_ {P1} $). The …

We present N-body simulations of a Sagittarius (Sgr)-like dwarf spheroidal galaxy that
follows its orbit about the Milky Way (MW) since its first crossing of the Galaxy's virial radius …

We present a panoramic map of the stellar streams of the Milky Way based upon astrometric
and photometric measurements from the Gaia DR2 catalogue. In this first contribution, we …

The question of whether galaxy mergers are linked to the triggering of active galactic nuclei
(AGN) continues to be a topic of considerable debate. The issue can be broken down into …

We present the host galaxies of four apparently nonrepeating fast radio bursts (FRBs), FRB
20181223C, FRB 20190418A, FRB 20191220A, and FRB 20190425A, reported in the first …

ABSTRACT SPIDERS (The SPectroscopic IDentification of eROSITA Sources) is a large
spectroscopic programme for X-ray selected galaxy clusters as part of the Sloan Digital Sky …

The Cluster HEritage project with XMM-Newton–Mass Assembly and Thermodynamics at
the Endpoint of structure formation (CHEX-MATE) is a three-mega-second Multi-Year …

We have designed a powerful new algorithm to detect stellar streams in an automated and
systematic way. The algorithm, which we call the STREAMFINDER, is well suited for finding …
