Evolution of Broad-line Emission from Active Galactic Nuclei
Moshe Elitzur, Luis C. Ho, Jonathan R. Trump
Apart from viewing-dependent obscuration, intrinsic broad-line emission from active galactic nuclei (AGNs) follows an evolutionary sequence: Type …
Unveiling the Structure of Barred Galaxies at 3.6 with the Spitzer Survey of Stellar Structure in Galaxies (SG): I. Disk Breaks
Taehyun Kim, Dimitri A. Gadotti, Kartik Sheth +24
We have performed two-dimensional multicomponent decomposition of 144 local barred spiral galaxies using 3.6 images from the Spitzer Survey of Stellar Structure in Galax…
Embedded Star Formation in S4G Galaxy Dust Lanes
Debra M. Elmegreen, Bruce G. Elmegreen, Santiago Erroz-Ferrer +22
Star-forming regions that are visible at 3.6 microns and Halpha but not in the u,g,r,i,z bands of the Sloan Digital Sky survey (SDSS), are measured in five nearby spiral galaxies t…
UM 625 Revisited: Multiwavelength Study of A Seyfert 1 Galaxy with a Low-mass Black Hole
Ning Jiang, Luis C. Ho, Xiao-bo Dong +2
UM 625, previously identified as a narrow-line active galactic nucleus (AGN), actually exhibits broad \ha\ and \hb\ lines whose width and luminosity indicate a low black hole mass…
