: Constraining the photometric redshifts of quasars using variability

Sarath Satheesh-Sheeba, Roberto J. Assef, Timo Anguita, Paula Sánchez-Sáez et autres

The Vera C. Rubin Observatory’s Legacy Survey of Space and Time (LSST) is expected to obtain observations of over ten million quasars. The survey’s exceptional cadence and sensitivity will enable a significant fraction of these objects to be monitored in the ugrizy …

CIV wind properties of the SDSS-V X-ray selected quasars: strong optical-to-UV emission is key regardless of X-ray strength

Amy L. Rankine, D. Homan, James Aird, Pranavi Hiremath et autres

We present an investigation of the rest-frame optical/UV and X-ray properties for a sample of 3027 X-ray selected quasars between $1.5 \leq z \leq 3.5$ detected in the deepest Spectrum Roentgen Gamma/eROSITA data available and observed by the fifth iteration of the …

COSMOS Spectroscopic Redshift Compilation (First Data Release): 488,000 Redshifts Encompassing Two Decades of Spectroscopy

Ali Ahmad Khostovan, Jeyhan S. Kartaltepe, M. Salvato, Olivier Ilbert et autres

We present the COSMOS Spectroscopic Redshift Compilation encompassing similar to 20 yr of spectroscopic redshifts within a 10 deg(2) area centered on the 2 deg(2) COSMOS legacy field. This compilation contains 487,666 redshifts of 266,284 unique objects from 138 individual programs up …

Sloan Digital Sky Survey. V. Pioneering Panoptic Spectroscopy

Juna A. Kollmeier, Hans-Walter Rix, Conny Aerts, James Aird et autres

Abstract The Sloan Digital Sky Survey V (SDSS-V) is pioneering panoptic spectroscopy: it is the first all-sky, multiepoch, optical-to-infrared spectroscopic survey. SDSS-V is mapping the sky with multiobject spectroscopy (MOS) at telescopes in both hemispheres (the 2.5 m Sloan Foundation Telescope at …

Characterizing the X-ray variability of QSOs to the highest Eddington ratios and black hole masses with eROSITA light curves

A. Georgakakis, A. Ruiz, J. Buchner, I. E. Papadakis et autres

ABSTRACT An important diagnostic of the inner structure of accretion flows onto supermassive black holes are the stochastic flux variations at X-ray wavelengths. Despite its significance, a systematic characterization of the statistical properties of the X-ray variability to the highest Eddington ratios …

Euclid Quick Data Release (Q1). Spectroscopic unveiling of highly ionised lines at z = 2.48-3.88

Euclid Collaboration, D Vergani, S Quai, F. Ricci et autres

This study explores a rare population of sources in a currently uncharted region of spectroscopic redshift space in the Euclid Quick Data Release (Q1), and is intended potentially to support upcoming spectroscopic studies. Our goal is to identify and investigate a population …
