FIGS: Spectral fitting constraints on the star formation history of massive galaxies since Cosmic Noon
Ignacio Ferreras, Anna Pasquali, Nor Pirzkal +16
We constrain the stellar population properties of a sample of 52 massive galaxies, with stellar mass log Ms>10.5, over the redshift range 0.5<z<2 by use of observer-frame optical a…
JWST Reveals Compact Nuclear Starbursts Masquerading as AGNs in Metal-Poor Dwarfs: Where Are the Accreting Intermediate-Mass Black Holes?
William Matzko, Shobita Satyapal, Jeffrey D. Mckaig +19
We present JWST/NIRSpec spectroscopy of the low-mass, metal-poor galaxy SDSS~J160135.95+311353.7 (J1601), selected for its extreme mid-infrared colors and compact nuclear emission,…
Nuclear Activity in the Low Metallicity Dwarf Galaxy SDSS J0944-0038: A Glimpse into the Primordial Universe
Michael Reefe, Shobita Satyapal, Remington O. Sexton +11
Local low metallicity dwarf galaxies are relics of the early universe and hold clues into the origins of supermassive black holes (SMBHs). In recent work, coronal lines have been u…
Mid-Infrared and Submillimeter Observations of the Illuminating Source of McNeil's Variable Nebula
Sean M. Andrews, Barry Rothberg, Theodore Simon
We present post-outburst observations of the mid-infrared spectrum and submillimeter continuum of the illuminating source of the newly-discovered McNeil's Nebula in the L1630 regio…
Buried AGNs in Advanced Mergers:Mid-infrared color selection as a dual AGN finder
Shobita Satyapal, Nathan J. Secrest, Claudio Ricci +7
A direct consequence of hierarchical galaxy formation is the existence of dual supermassive black holes (SMBHs), which may be preferentially triggered as active galactic nuclei (AG…
Unveiling The Sigma-Discrepancy II: Revisiting the Evolution of ULIRGs & The Origin of Quasars
Barry Rothberg, Jacqueline Fischer, Myriam Rodrigues +1
We present the first central velocity dispersions (sigma_o) measured from the 0.85 micron Calcium II Triplet (CaT) for 8 advanced (i.e. single nuclei) local (z < 0.15) Ultraluminou…
