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…
Halfway to the Peak: The JWST MIRI 5.6 micron number counts and source population
Leonid Sajkov, Anna Sajina, Alexandra Pope +9
We present an analysis of eight JWST Mid-Infrared Instrument (MIRI) 5.6 micron images with depths of ~0.1 uJy. We detect 2854 sources within our combined area of 18.4 squar…
Predicting the spectrum of UGC 2885, Rubin's Galaxy with machine learning
Benne W. Holwerda, John F. Wu, William C. Keel +10
Wu & Peek (2020) predict SDSS-quality spectra based on Pan-STARRS broad-band \textit{grizy} images using machine learning (ML). In this letter, we test their prediction for a uniqu…
Halfway to the Peak: Kinematic Signatures of Stable Rotating Disks in Luminous Infrared Galaxies at z=0.5-0.6
Miriam Eleazer, Alexandra Pope, Anna Sajina +13
We present a kinematic study of six infrared-luminous galaxies observed with the Mid-InfraRed Instrument Medium-Resolution Spectrometer (MIRI/MRS) onboard JWST. These galaxies lie…
Halfway to the Peak: ice absorption bands at with JWST MIRI/MRS
Anna Sajina, Alexandra Pope, Henrik Spoon +9
This paper presents the first combined detections of CO, CO, XCN and water ices beyond the local Universe. We find gas-phase CO in addition to the solid phase CO. Our source, S…
