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…
