JADES data release 4 – Paper I . Sample selection, observing strategy and redshifts of the complete spectroscopic sample

Euclid Quick Data Release (Q1)

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 Noon Galaxies in the Hubble Ultra Deep Field with MIRI Wide-Field Slitless Spectroscopy

We present results from a survey of the Hubble Ultra-Deep Field using the Wide-Field Slitless Spectroscopic (WFSS) capability of the Mid-Infrared Instrument (MIRI) on JWST, demonstrating the capabilities of this new mode. We describe the data reduction and calibration methodology, and estimate calibration uncertainties...

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...

A search for high-redshift radio galaxy candidates with the MeerKAT Galaxy Cluster Legacy Survey

High-redshift radio galaxies (HzRGs) are among the earliest and most massive galaxies whose powerful radio emission allows us to probe the large-scale structure, galaxy evolution, and the epoch of reionisation. We present a new sample of HzRG candidates constructed using the 1.28 GHz data from the MeerKAT Galaxy Clus...

The GLEAM 4-Jy (G4Jy) Sample: V. Broadband spectral analysis

The G4Jy Sample consists of 1,863 of the brightest sources in the southern sky, as selected at 151 MHz using the GaLactic and Extragalactic All-sky MWA (GLEAM) survey. We supplement existing, low-frequency radio data by completing visual inspection of radio images from the Rapid ASKAP Continuum Survey (RACS) at 887.5,...
