The Twentieth Data Release of the Sloan Digital Sky Survey: First All-Sky BOSS Spectra, eROSITA-SDSS-V Mapper Coordinated Observations, and a Preview of the Local Volume Mapper

SDSS Collaboration, Mojgan Aghakhanloo, David Aguilar +273

The paper describes the twentieth data release (DR20) of the Sloan Digital Sky Survey, providing over 3 million new optical spectra from the SDSS‑V Milky Way, Black Hole, and Local…

Low-Metallicity Star Formation Survey in Sh2-284 (LZ-STAR): The Core Mass Function

Yu Cheng, Jonathan C. Tan, Morten Andersen +4

The authors use ALMA 1.3 mm dust continuum observations of the low‑metallicity star‑forming region Sh2‑284 to identify dense cores and measure the core mass function, finding a hig…

Expansion kinematics of young clusters. III. The kiloparsec sample

Joseph J. Armstrong, Jonathan C. Tan

We combine Gaia DR3 5-parameter astrometry with calibrated radial velocities for 23 nearby (<1 kpc) young (<60 Myr) clusters, with membership lists from Cantat-Gaudin et al. (2020)…

Low cosmic-ray ionisation at parsec scales in G035.39-00.33

Andrea Socci, Ashley Barnes, Jaime Pineda +11

Cosmic rays (CRs) regulate the chemical evolution of the gas and its coupling to the magnetic field in the densest and coldest regions of the interstellar medium (ISM). However, th…

Fireworks at Cosmic Dawn: relieving BAO-CMB tensions with the Pop III.1 Flash

Yash Aggarwal, Christopher Cain, Garett Lopez +4

A Cosmic Microwave Background (CMB) optical depth of , several in excess of the latest Planck low- EE polarization measurement, has been proposed as a way t…

The Impact of Population III.1 Flash Reionization for CMB Polarization and Thomson Scattering Optical Depth

Jonathan C. Tan, Eiichiro Komatsu

The Population III.1 theory for supermassive black hole (SMBH) formation predicts a very early () transient phase, the ``Pop III.1 Flash'', of cosmic reionization power…
