(Re)solving the Complex Multiscale Morphology and V-shaped Spectral Energy Distribution of a Newly Discovered Strongly Lensed Little Red Dot in A383
Josephine F. W. Baggen, Pieter van Dokkum, Ivo Labbé +1
The paper reports JWST NIRCam observations of a strongly lensed, luminous "little red dot" galaxy at redshift 6.0 behind the cluster A383, revealing a complex morphology with disti…
How can we finally see the first light? Status and perspective in the search for Population III stars
Alessandra Venditti, Daniel Schaerer, Erik Zackrisson +28
Finding the first (Population III or Pop III) stars is one of the fundamental quests of astronomy, aiming to deliver the missing link in how stars form at early cosmic times. Yet t…
The Impact of Baryonic Effects on the Dynamical Masses Inferred Using Satellite Kinematics
Josephine F. W. Baggen, Frank C. van den Bosch, Kaustav Mitra
Satellite kinematics offers a powerful method to infer dynamical halo masses and has been demonstrated to yield tight constraints on the galaxy-halo connection. However, previous s…
BASILISK IV. No Tension with Satellite Kinematics
Kaustav Mitra, Frank C. van den Bosch, Josephine Baggen +1
We develop a novel technique to probe the tension, using information from the smallest scales of galaxy redshift survey data. Specifically, we use Basilisk, a Bayesian hierar…
Irony at z=6.68: a bright AGN with forbidden Fe emission and multi-component Balmer absorption
Francesco D'Eugenio, Erica Nelson, Xihan Ji +11
We present the deepest medium-resolution JWST/NIRSpec spectroscopy to date of a bright Little Red Dot (LRD) AGN, Irony at z=6.68. The data reveal broad Balmer emission from H-H…
Further Evidence for a Direct-Collapse Origin of the Supermassive Black Hole at the Center of the Infinity Galaxy
Pieter van Dokkum, Gabriel Brammer, Connor Jennings +2
The z=1.14 galaxy consists of two ringed nuclei with an active supermassive black hole (SMBH) in between them. The system is likely the result of a nearly face-on collisio…
