KCWI Discovery of a Spatially Resolved Kpc-Scale Ionized Outflow in NGC 1275

Kylie Yui Dan, Hanae Inami, Thomas Bohn +5

We present new Keck Cosmic Web Imager observations of the central few kiloparsecs of NGC 1275, the brightest cluster galaxy of the Perseus Cluster. These integral field spectroscop…

Clumpy Disk, Interloper, or Merger? Nature of a Distant Galaxy Pair at 5 kpc Projected Separation

Hajar Aziz, Vivian U, Archana Aravindan +8

We present the morphological, photometric, and spectroscopic properties of a z ~ 1 galaxy, "lil gal", serendipitously detected in JWST Mid Infrared Instrument (MIRI) images of near…

Observed Timescales of Stellar Feedback in Star-Forming, Low-Mass Galaxies

Laura C. Hunter, Liese van Zee, Roger E. Cohen +5

Understanding the timescales of atomic gas turbulence is crucial to understanding the interplay between star formation and the interstellar medium (ISM). To investigate the timesca…

A precessing jet from an active galactic nucleus drives gas outflow from a disk galaxy

Justin A. Kader, Vivian U, Loreto Barcos-Muñoz +30

To reproduce observed galaxy properties, cosmological simulations require that massive galaxies experience feedback from active galactic nuclei, which regulates star formation with…

The Milky Way Bulge Extra-Tidal Star Survey: NGC 6569

Joanne Hughes, Andrea Kunder, Kevin Covey +25

We present spectroscopic evidence for tidal debris associated with the bulge globular cluster NGC 6569, based on medium-resolution (R ~ 11,000) Anglo-Australian Telescope spectra o…

Shockingly Effective: Cluster Winds as Engines of Feedback in Starburst Galaxy VV 114

Justin A. Kader, Vivian U, Jeffrey A. Rich +29

We present high-resolution Keck Cosmic Web Imager (KCWI) and MUSE IFU spectroscopy of VV 114, a local infrared-luminous merger undergoing a vigorous starburst and showing evidence…
