Shocked POststarburst Galaxy Survey. IV. Outflows in Shocked Post-Starburst Galaxies Are Not Responsible For Quenching
Antoniu Fodor, Taylor Tomko, Mary Braun +13
Shocked POst-starburst Galaxies (SPOGs) exhibit both emission lines suggestive of shock-heated gas and post-starburst-like stellar absorption, resulting in a unique subset for gala…
The JWST EXCELS survey: direct estimates of C, N, and O abundances in two relatively metal-rich galaxies at
K. Z. Arellano-Córdova, F. Cullen, A. C. Carnall +14
We present a spectroscopic analysis of two star-forming galaxies at observed with JWST/NIRSpec as part of the EXCELS survey. The detection of the CIII]~1906,09, [OII…
High-velocity outflows persist up to 1 Gyr after a starburst in recently-quenched galaxies at z > 1
Elizabeth Taylor, David Maltby, Omar Almaini +4
High-velocity outflows are ubiquitous in star-forming galaxies at cosmic noon, but are not as common in passive galaxies at the same epoch. Using optical spectra of galaxies select…
Galaxy evolution in the post-merger regime. II -- Post-merger quenching peaks within 500 Myr of coalescence
Sara L. Ellison, Leonardo Ferreira, Vivienne Wild +3
(Abridged) Mechanisms for quenching star formation in galaxies remain hotly debated, with galaxy mergers an oft-proposed pathway. In Ellison et al. (2022) we tested this scenario b…
Measuring the ISM Content of Nearby, Luminous, Type 1 and Type 2 QSOs through CO and [C II]
Yuanze Luo, A. O. Petric, R. M. J. Janssen +18
We present observations of CO(1--0) and CO(2--1) lines from the Institut de radioastronomie millimétrique (IRAM) 30m telescope toward 20 nearby, optically luminous type 2 quasars (…
Pulling back the curtain on shocks and star-formation in NGC 1266 with Gemini-NIFS
Justin Atsushi Otter, Katherine Alatalo, Kate Rowlands +21
We present Gemini near-infrared integral field spectrograph (NIFS) K-band observations of the central 400 pc of NGC 1266, a nearby (D30 Mpc) post-starburst galaxy with a p…
