An HST survey of photometry and multiplicity of brown dwarfs and planetary-mass objects in the field of Taurus
Pengyu Liu, Beth A. Biller, Clémence Fontanive +11
We present a photometric and multiplicity survey of 26 young objects with masses between 6 Mj and 37 Mj and spectral type later than M8 in the Taurus star-forming region with the H…
Mapping Gas Accretion and Stellar Kinematics to Sub-kiloparsec Scales in NGC 4696 with JWST/NIRSpec
Mathieu Marquis, Julie Hlavacek-Larrondo, Olivia Pereira +35
We present JWST/NIRSpec IFU spectroscopy of the central pc () of NGC 4696, the BCG in the Centaurus cluster. Leveraging the (…
Two Exciting High-redshift Galaxy Candidates Turn Out to Be Two Exciting Ultra-cool Brown Dwarfs
Maruša Bradač, Chris Willott, Yoshihisa Asada +37
From the onset of observations of JWST we have discovered unexpectedly luminous galaxies at redshifts and as high as . With their discovery, the question immediately f…
The Y Dwarf Population with HST: unlocking the secrets of our coolest neighbours -- III. Near-Infrared Photometry
Clémence Fontanive, Luigi R. Bedin, Mark W. Phillips +4
Y dwarfs represent the coldest class of brown dwarfs, with effective temperatures below 500K, and provide unique analogues to cold giant exoplanets. We present a large compilation…
The Y Dwarf Population with HST: unlocking the secrets of our coolest neighbours -- II. Parallaxes and Proper Motions
Clémence Fontanive, Luigi R. Bedin, Loïc Albert +1
We present astrometric results from a Hubble Space Telescope (HST) campaign aimed at determining precise distances for cold Y-type brown dwarfs. Combining observations from a dedic…
