HI Observations of Giant Low Surface Brightness Galaxies
Philip Lah, Nikhil Arora, Ivan Yu. Katko +5
Giant low surface brightness galaxies (gLSBs) are galaxies with extremely extended, faint, optical disks over 50 kpc in radius and have high total masses which can reach 10^12 sola…
Stellar CoRGI in MaNGA: Stellar Counterrotating Galaxies Identified in the MaNGA Survey
Damir Gasymov, Ivan Yu. Katkov, Evgenii V. Rubtsov +8
Stellar counterrotating (CR) galaxies are systems hosting two large-scale stellar components rotating in opposite directions -- a main, preexisting galaxy body with an older stella…
Unified Spectrospatial Forward Models: Spatially Continuous Maps of Weak Emission Lines in the Rosette Nebula with SDSS-V LVM
Thomas Hilder, Andrew R. Casey, Julianne J. Dalcanton +14
Analyses of IFU data are typically performed on a per-spaxel basis, with each spectrum modelled independently. For low signal-to-noise (S/N) features such as weak emission lines, e…
NGC 3259: A Signal for an Untapped Population of Slowly Accreting Intermediate-Mass Black Holes
Kirill A. Grishin, Igor V. Chilingarian, Francoise Combes +4
Low-mass active galactic nuclei (AGNs) can provide important constraints on the formation and evolution of supermassive black holes (SMBHs), a central challenge in modern cosmology…
