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…

Phase II of the Keck Planet Imager and Characterizer: system-level laboratory characterization and preliminary on-sky commissioning

Daniel Echeverri, Nemanja Jovanovic, Jacques-Robert Delorme +35

The Keck Planet Imager and Characterizer (KPIC) is a series of upgrades for the Keck II Adaptive Optics (AO) system and the NIRSPEC spectrograph to enable diffraction-limited, high…

Retrieving C and O Abundance of HR 8799 c by Combining High- and Low-Resolution Data

Ji Wang, Jason J. Wang, Jean-Baptiste Ruffio +29

The formation and evolution pathway for the directly-imaged multi-planetary system HR 8799 remains mysterious. Accurate constraints on the chemical composition of the planetary atm…

GOALS-JWST: Resolving the Circumnuclear Gas Dynamics in NGC 7469 in the Mid-Infrared

Vivian U, Thomas Lai, Marina Bianchin +35

The nearby, luminous infrared galaxy (LIRG) NGC 7469 hosts a Seyfert nucleus with a circumnuclear star-forming ring and is thus the ideal local laboratory for investigating the sta…

GOALS-JWST: Mid-Infrared Spectroscopy of the Nucleus of NGC 7469

L. Armus, T. Lai, V. U +32

We present mid-infrared spectroscopic observations of the nucleus of the nearby Seyfert galaxy NGC 7469 taken with the MIRI instrument on the James Webb Space Telescope (JWST) as p…

A Clear View of a Cloudy Brown Dwarf Companion from High-Resolution Spectroscopy

Jerry W. Xuan, Jason Wang, Jean-Baptiste Ruffio +37

Direct imaging studies have mainly used low-resolution spectroscopy () to study the atmospheres of giant exoplanets and brown dwarf companions, but the presence of clo…

Retrieving the C and O Abundances of HR 7672~AB: a Solar-Type Primary Star with a Benchmark Brown Dwarf

Ji Wang, Jared R. Kolecki, Jean-Baptiste Ruffio +30

A benchmark brown dwarf (BD) is a BD whose properties (e.g., mass and chemical composition) are precisely and independently measured. Benchmark BDs are valuable in testing theoreti…
