The detections of gravitational waves from compact binary
mergers and the followup observations of electromagnetic emissions
together provide a powerful and independent tool to explore the
Universe. With successive upgrades to the LIGO and Virgo...
JWST, the most powerful and complex telescope ever designed for
space, was just successfully launched and deployed by NASA after 30
years in development. JWST is, in part, a successor to the Hubble
Space Telescope, but is unique in its infrared...
Most of the exoplanets (4,651+) discovered to date were detected
by looking for tiny diminutions in a star’s visible light when a
non-luminous object transits in front of it. Almost all exoplanets
and exoplanet candidates are within 3,000 light...
Abstract 1: The CDM scenario predicts an entire hierarchy of
dark substructure within the Milky Way halo that is, barring any
annihilation signal, only detectable gravitationally. Cold tidal
streams from disrupting globular clusters have been...
The smallest and faintest galaxies around the Milky Way are the
most ancient, most metal-poor, and most dark-matter-dominated
systems known. These extreme objects offer unique access to small
scales where the stellar and dark matter content can be...
Gravitational waves (GW) from compact binary coalescences are
natural cosmological probes. On the one hand, these standard siren
sources provide direct measurements of luminosity distance. In
addition, features in the mass distribution, such as mass...
