AMIGO: a Data-Driven Calibration of the JWST Interferometer
Louis Desdoigts, Benjamin Pope, Max Charles +8
The James Webb Space Telescope (JWST) hosts a non-redundant Aperture Masking Interferometer (AMI) in its Near Infrared Imager and Slitless Spectrograph (NIRISS) instrument, providi…
Euclid: Scaled-up little red dots and other sources with v-shaped spectral energy distributions at z>4
Euclid Collaboration, A. A. Tumborang, K. I. Caputi +169
Little Red Dots (LRDs) are some the most intriguing galaxy populations recently identified at z>~4 with JWST. They constitute the most extreme class of a more abundant population o…
JWST Reveals Two Overmassive Black Hole Candidates in Dwarf Galaxies at z 0.7: Pushing Black Hole Searches into the Dwarf-Galaxy Regime
E. Iani, P. Rinaldi, A. Torralba +35
We report the discovery and characterization of two compact galaxies, Pelias and Neleus, at z ~ 0.71 and z ~ 0.75, identified in MACS J0416.1-2403 and GOODS-North. Both exhibit unu…
The JWST Early Release Science Program for Direct Observations of Exoplanetary Systems III: Aperture Masking Interferometric Observations of the star HIP 65426 at 3.8 um
Shrishmoy Ray, Steph Sallum, Sasha Hinkley +121
We present aperture masking interferometry (AMI) observations of the star HIP 65426 at as a part of the JWST Direct Imaging Early Release Science (ERS) program obta…
