Spatial decomposition of Little Red Dots with JWST/NIRSpec IFU into broad-line red cores and narrow-line blue host galaxies
Yuzo Ishikawa, Anna-Christina Eilers, Rohan P. Naidu +11
Little Red Dots (LRDs) are a population of compact red sources discovered by the James Webb Space Telescope (JWST). Imaging and spectroscopy have shown that LRDs exhibit a complex…
Little Red Dots at z~2 in EIGER reveal a gentle decline with respect to their peak number density at z~5
Shrriya Kapoor, Jorryt Matthee, Alberto Torralba +10
We report the discovery of a sample of little red dots (LRDs) at identified from deep JWST/NIRCam imaging and wide-field slitless spectroscopy over arcmin f…
The MASSIVE SURVEY XXI: Local Variations in the Stellar Initial Mass Function of MASSIVE Early-Type Galaxies
Meng Gu, Jenny E. Greene, Andrew B. Newman +2
Extensive evidence suggests that the stellar initial mass function (IMF) varies among early-type galaxies (ETGs), but spatially resolved studies within individual galaxies are limi…
Constraints on the Gas Geometry Surrounding Little Red Dots through Narrow-Line Diagnostics
Visal Sok, Erica J. Nelson, Mitchell C. Begelman +10
Little Red Dots (LRDs) are a recently identified population of high-redshift sources, with a common interpretation being accreting black holes embedded within a spherical, opticall…
Extended [CII] gas emission in and around a massive quiescent galaxy at z=7.3
F. Valentino, A. Pensabene, A. Weibel +16
We report the discovery of [CII] 158 micron emission in and around the most distant known massive quiescent galaxy RUBIES-UDS-QG-z7 at z = 7.27. Observed with ALMA in band 6, the […
A Black Hole Star at Cosmic Noon: Extreme Balmer break, photospheric continuum, and broad absorption by thick winds in a Little Red Dot at z=1.7
Alberto Torralba, Jorryt Matthee, Andrea Weibel +12
Recent studies at high redshift have revealed an enigmatic class of Little Red Dots (LRDs) with extreme Balmer breaks, stronger than in any stellar atmosphere. However, it is uncle…
