VENUS: When Red meets Blue -- A multiply imaged Little Red Dot with an apparent blue companion behind the galaxy cluster Abell 383

Miriam Golubchik, Lukas J. Furtak, Joseph F. V. Allingham +50

We report the discovery of a doubly-imaged Little Red Dot (LRD) candidate behind the galaxy cluster Abell 383, which we dub A383-LRD1. Initially classified as a dropout galaxy in H…

Shining a Light on the Connections between Galactic Outflows Seen in Absorption and Emission Lines

Xinfeng Xu, Alaina Henry, Timothy Heckman +14

Galactic outflows provide important feedback effects to regulate the evolution of host galaxies. Two primary diagnostics of outflows are broad and/or blueshifted emission and absor…

The Ultraviolet Slopes of Early Universe Galaxies: The Impact of Bursty Star Formation, Dust, and Nebular Continuum Emission

Desika Narayanan, Daniel P. Stark, Steven L. Finkelstein +8

JWST has enabled the detection of the UV continuum of galaxies at z>10, evidencing a population of extremely blue, potentially dust-free galaxies. Interpreting the UV spectra of ga…

Theoretical strong line metallicity diagnostics for the JWST era

Prerak Garg, Desika Narayanan, Ryan L. Sanders +5

The ratios of strong rest-frame optical emission lines are the dominant indicator of metallicities in high-redshift galaxies. Since typical strong-line based metallicity indicators…

CLASSY VI: Density, Structure and Size of Galactic Outflows

Xinfeng Xu, Timothy Heckman, Alaina Henry +12

Galaxy formation and evolution are regulated by the feedback from galactic winds. Absorption lines provide the most widely available probe of winds. However, since most data only p…

The Hawk-I UDS and GOODS Survey (HUGS): Survey design and deep K-band number counts

A. Fontana, J. S. Dunlop, D. Paris +40

We present the results of a new, ultra-deep, near-infrared imaging survey executed with the Hawk-I imager at the ESO VLT, of which we make all the data public. This survey, named H…
