When Jets Don't Quench: Near-Infrared H in Star Forming Low-Excitation Radio Galaxies
Swetha Sankar, Andreea O. Petric, Debora Pelliccia +11
We present new Gemini/GNIRS near-infrared spectroscopic observations of eight low-redshift () blue low-excitation radio galaxies (BLERGs), a rare subset ( of l…
XRISM detection of the 6.4 keV Fe K line in the radio galaxy Cygnus A
Anwesh Majumder, T. Heckman, L. Gu +7
We detail the spectral analysis of a 170 ks XRISM Resolve observation of the core of Cygnus A. The high spectral resolution of Resolve have enabled us to probe the inner accretion…
Tracing Radio AGN-Driven Quenching in Post-Starburst Galaxies at Cosmic Noon
Pallavi Patil, Kate Rowlands, Katherine Alatalo +14
We present a radio continuum study of photometrically selected cosmic noon (0.5<z<3) post-starburst galaxies (PSBs) in the UKIDSS Deep Survey (UDS) field to assess if radio-mode Ac…
A Multiwavelength Evaluation of AGN in the Post-Starburst Phase
Yuanze Luo, Kate Rowlands, Katherine Alatalo +14
The quenching of star formation is a crucial phase in galaxy evolution. Although active galactic nuclei (AGN) feedback has been proposed as a key driver of this transition, the lac…
Clumpy, dense gas in the outflow of NGC 1266
Justin Atsushi Otter, Katherine Alatalo, Kate Rowlands +23
Outflows are one of the most spectacular mechanisms through which active galactic nuclei (AGN) impact their host galaxy, though the role of AGN-driven outflows in global star forma…
What drives kpc-scale outflows in Radio-Quiet AGN? Insights from a Polarimetric Study
Salmoli Ghosh, Preeti Kharb, Biny Sebastian +5
We present a review of our findings on the origin, drivers, nature, and impact of kiloparsec-scale radio emission in radio-quiet (RQ) AGN. Using radio polarimetric techniques, we p…
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…
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…
EDGE-CALIFA survey: Self-regulation of Star formation at kpc scales
J. K. Barrera-Ballesteros, S. F. Sánchez, T. Heckman +11
We present the relation between the star formation rate surface density, , and the hydrostatic mid-plane pressure, P, for 4260 star-forming regions of kpc si…
SDSS-IV MANGA: A Star Formation -- Baryonic Mass Relation at Kpc Scales
J. K. Barrera-Ballesteros, T. Heckman, S. F. Sanchez +11
Star formation rate density, , has shown a remarkable correlation with both components of the baryonic mass at kpc scales (i.e., the stellar mass density, and the mole…
Disentangling AGN and Star Formation in Soft X-rays
Stephanie M. LaMassa, T. M. Heckman, A. Ptak
We have explored the interplay of star formation and AGN activity in soft X-rays (0.5-2 keV) in two samples of Seyfert 2 galaxies (Sy2s). Using a combination of low resolution CCD…
Exploring the Connection Between Star Formation and AGN Activity in the Local Universe
Stephanie M. LaMassa, T. M. Heckman, A. Ptak +3
We study a combined sample of 264 star-forming, 51 composite, and 73 active galaxies using optical spectra from SDSS and mid-infrared (mid-IR) spectra from the Spitzer Infrared Spe…
Penetrating the Deep Cover of Compton Thick Active Galactic Nuclei
N. A. Levenson, T. M. Heckman, J. H. Krolik +2
We analyze observations obtained with the Chandra X-ray Observatory of bright Compton thick active galactic nuclei (AGNs), those with column densities in excess of 1.5 x 10^{24} cm…
Deconstructing NGC 7130
N. A. Levenson, K. A. Weaver, T. M. Heckman +2
Observations of the Seyfert 2 and starburst galaxy NGC 7130 with the Chandra X-ray Observatory illustrate that both of these phenomena contribute significantly to the galaxy's dete…
