Validating z > 7.5 Lyman Break Galaxy candidates in the COSMOS field with JWST/PASSAGE

Zoke W. Sackih, Mason S. Huberty, Claudia Scarlata +9

We analyze spectroscopy from one NIRISS pointing in the JWST-PASSAGE program for seven candidate photometrically-selected COSMOS-Web sources. We spectroscopically c…

Revisiting the mass metallicity relation and the fundamental metallicity relation of dwarf galaxies at cosmic noon with NIRISS

Xianlong He, Zihao Li, Xin Wang +6

We extend the stellar-mass gas-phase metallicity relation (MZR) at down to the extremely low-mass regime using 183 galaxies with , based…

Can BLR line profile shape improve single-epoch black hole mass estimates?

Lizvette Villafaña, Tommaso Treu, Shu Wang +7

The virial coefficient (), which is meant to encapsulate broad-line region (BLR) geometry and kinematics, remains one of the largest sources of systematic uncertainty in black h…

Wild is the wind from low-luminosity AGN: a jet-driven gas bubble blowing out a massive CO-dark outflow in ESO 420-G13

J. A. Fernández-Ontiveros, L. Spinoglio, M. Pereira-Santaella +8

We present JWST/MIRI mid-infrared integral field spectroscopy combined with ALMA CO(2-1) observations of the post-starburst galaxy ESO 420-G13, hosting a low-luminosity AGN. The un…

Galaxy Zoo: Cosmic Dawn -- morphological classifications for over 41,000 galaxies in the Euclid Deep Field North from the Hawaii Two-0 Cosmic Dawn survey

James Pearson, Hugh Dickinson, Stephen Serjeant +22

We present morphological classifications of over 41,000 galaxies out to across six square degrees of the Euclid Deep Field North (EDFN) from the Hawaii Twenty…

The Narrow Emission Lines of Seyfert 1 Galaxies: Comparisons with a Large SDSS Sample

Matthew Malkan, Lisbeth Jensen, Lei Hao

We analyzed a large sample of SDSS spectra of Seyfert galaxies, subdividing Seyfert 1s based on their narrow-to-broad Halpha components. Comparing their narrow-lines (NL) to Seyfer…
