Ripples in the OCEANS: Broad Line Variability of Little Red Dots

Madisyn Brooks, Kelcey Davis, Jonathan R. Trump +16

Little Red Dots (LRDs) are a unique class of compact, red sources discovered in the JWST extragalactic deep fields. Determining if they are indeed powered by accreting supermassive…

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…

Discovery of a Barred-Spiral Galaxy at = 3.16 II. The Star Formation History

Yingjie Cheng, Mauro Giavalisco, Daniel Ivanov +6

We present a detailed analysis of a massive barred galaxy at using deep multi-band imaging from HST and JWST. For the first time, we resolve its morphology and st…

Discovery of a Barred-Spiral Galaxy at = 3.16 I: Bar Identification and Properties

Daniel Ivanov, Mauro Giavalisco, Yingjie Cheng +6

The formation of stellar bars is an important milestone in the secular evolution of spiral galaxies, which typically indicates the presence of a massive rotationally supported disk…

Compact Core, Extended Reach: A Bipolar kpc-Scale Elongation in a Little Red Dot at

Zhiyuan Ji, Yang Sun, Mauro Giavalisco +7

Little Red Dots (LRDs) appear extremely compact at rest-frame optical wavelengths, yet many show extended rest-frame UV morphology revealing more complex internal structure. We pre…

Exploring the Relationship Between Bars, Star Formation Activity, and Host Galaxy Properties from to

Eden Wise, Shardha Jogee, Yuchen Guo +20

We present the most comprehensive study to date of the relationship between bars, star formation, and galaxy properties from 0 to 2. We use a mass-complete sample…
