A VLA Study of the Disturbed Massive Cluster PLCK G165.7 + 67.0 and Its Two Narrow Angle Tail Galaxies

Aurora Wilde, Eric F. Jimenez-Andrade, Brenda L. Frye +11

Since spectroscopic measurements provide only the line-of-sight velocity, transverse motions are difficult to constrain. As a result, transverse velocities have so far been measure…

SN Helios: A Multiply Imaged Type II Supernova Opening Time-Delay Cosmography beyond redshift of 3

Seiji Fujimoto, Conor Larison, Justin D. R. Pierel +64

We report the discovery and spectroscopic confirmation of SN Helios, a strongly lensed, multiply imaged Type II supernova (SN) at behind the galaxy cluster RXC J0018.5+162…

A sub-100 pc view at z~5 of a Multiply-Imaged Massive Quiescent Galaxy

Richard Pan, Danilo Marchesini, Joseph F. V. Allingham +34

Recent James Webb Space Telescope spectroscopic surveys reveal an abundance of rapidly assembled early galaxies in the first billion years. Cosmological simulations struggle to rep…

EPOCHS-DR2 I: Expanded data release and properties of photometrically selected galaxies across NIRCam deep fields covering with the galfind software

Duncan Austin, Christopher J. Conselice, Thomas Harvey +14

We present the \epochstwo\ sample of star forming galaxies at produced using the \galfind\ photometric pipeline across $\sim650-740~\mathrm{arcmin}^2…

PEARLS: NuSTAR and XMM-Newton Extragalactic Survey of the JWST North Ecliptic Pole Time-Domain Field IV: X-Ray Variability Analysis

Ross Silver, Francesca Civano, Xiurui Zhao +31

NuSTAR and XMM-Newton have observed the James Webb Space Telescope (JWST) North Ecliptic Pole (NEP) Time-Domain Field (TDF) for almost five contiguous years starting in 2019. In th…

Constraints on the Pop III Sky Surface Brightness from High-Redshift Caustic Transients in MACS0416

Jakob P. Perivolotis, Pietro Bergamini, Rogier A. Windhorst +18

Population III (Pop III) stars are hypothetical zero-metallicity stellar structures formed from primordial hydrogen and helium. They are theorized to span a wide mass range, extend…
