Halfway to the peak: Spatially resolved star formation and kinematics in a z=0.54 dusty galaxy with JWST/MIRI
Jason Young, Alexandra Pope, Anna Sajina +16
We present JWST/MIRI/MRS observations of an infrared luminous disk galaxy, FLS1, at z=0.54. With a lookback time of 5 Gyr, FLS1 is chronologically at the midpoint between the peak…
Tracing the Total Stellar Mass and Star Formation of High-Redshift Protoclusters
Roxana Popescu, Alexandra Pope, Kyoung-Soo Lee +6
As the progenitors of present-day galaxy clusters, protoclusters are excellent laboratories to study galaxy evolution. Since existing observations of protoclusters are limited to t…
The IR Compactness of Dusty Galaxies Set Star-formation and Dust Properties at z~0-2
Jed McKinney, Alexandra Pope, Allison Kirkpatrick +9
Surface densities of gas, dust and stars provide a window into the physics of star-formation that, until the advent of high-resolution far-infrared/sub-millimeter observations, has…
ALMA reveals a stable rotating gas disk in a paradoxical low-mass, ultra-dusty galaxy at z = 4.274
Alexandra Pope, Jed McKinney, Patrick Kamieneski +13
We report ALMA detections of [CII] and dust continuum in Az9, a multiply-imaged galaxy behind the Frontier Field cluster MACSJ0717.5+3745. The bright [CII] emission line provides a…
UV-FIR SED modeling of AGN in IR-luminous galaxies up to z~2.5: Understanding the effects of torus models
Alyssa D. Sokol, M. Yun, A. Pope +2
UV-FIR SED modeling is an effective way to disentangle emission between star formation (SF) and active galactic nuclei (AGN) in galaxies; however, this approach becomes uncertain f…
Broad emission lines in optical spectra of hot dust-obscured galaxies can contribute significantly to JWST/NIRCam photometry
Jed McKinney, Luke Finnerty, Caitlin Casey +13
Selecting the first galaxies at z>7-10 from JWST surveys is complicated by z<6 contaminants with degenerate photometry. For example, strong optical nebular emission lines at z<6 ma…
