Euclid Quick Data Release (Q1)

Euclid Quick Data Release (Q1) Euclid spectroscopy of quasars. 2. Physical properties from spectral fitting

A substantial volume of spectroscopic data has become available with the Euclid Data Release (Q1), which represents a unique opportunity to study quasars (QSOs) in the Euclid Deep Fields, provide spectroscopic measurements, and estimates of their physical properties. We present results from a spectroscopic analysis of...

CHANG-ES XLI: Data Release 5—VLA C-configuration Images

We present Data Release 5 (DR5) of the Continuum Halos in Nearby Galaxies—an EVLA Survey (CHANG-ES), including select data products. These data were observed with the Karl G. Jansky Very Large Array (VLA) in C configuration, in the L band (1.575 GHz) and C band (6.0 GHz) for all 35 edge-on galaxies in the CHANG-ES samp...

Cosmic web Lyα emission in a sample of overdense regions

We present a complete and homogeneous analysis of the łya emission properties of the cosmic web at 3 łesssim z łesssim 5 as a function of the overdensity of Lyα emitters (LAEs) in the MUSE Ultra Deep Field (MUDF) and the MUSE Extremely Deep Field (MXDF). We identified 41 overdensities, probing environments that are δ ≈...

Low-redshift Interlopers in the SDSS DR16 z  >  5 Quasar Catalog

High-redshift quasars (z  >  5) are crucial for studying early black hole growth and reionization. Sloan Digital Sky Survey (SDSS) Data Release 16 catalogs 655 such sources with multiple redshift estimators. We systematically examined this subsample and found 480 sources (73.2%) where pipeline redshift (Z_DR16Q) disagr...

Euclid: Quick Data Release (Q1) -- Optical hotspots in powerful radio galaxies

The hotspots of powerful radio galaxies are the sites of high-energy particle acceleration, but radio observations give us limited information on the electron energy distributions that they generate, which affects our overall understanding of their physics and energetics. Optical synchrotron counterparts to radio galax...
