The ACS Nearby Galaxy Survey Treasury I. The Star Formation History of the M81 Outer Disk
Benjamin F. Williams, Julianne J. Dalcanton, Anil C. Seth +16
The ACS Nearby Galaxy Survey Treasury (ANGST) is a large Hubble Space Telescope (HST) Advanced Camera for Surveys (ACS) treasury program to obtain resolved stellar photometry for a…
The ACS Nearby Galaxy Survey Treasury II. Young Stars and their Relation to Halpha and UV Emission Timescales in the M81 Outer Disk
Stephanie M. Gogarten, Julianne J. Dalcanton, Benjamin F. Williams +11
We have obtained resolved stellar photometry from Hubble Space Telescope (HST) Advanced Camera for Surveys (ACS) observations of a field in the outer disk of M81 as part of the ACS…
The Rotating Nuclear Star Cluster in NGC 4244
Anil C. Seth, Robert D. Blum, Nate Bastian +3
We present observations of the nuclear star cluster in the nearby edge-on spiral galaxy NGC 4244 using the Gemini Near-Infrared Integral Field Spectrograph (NIFS) with laser guide…
Radio continuum observations of the candidate supermassive black hole in the dwarf elliptical VCC128
Pieter Buyle, Sven De Rijcke, Victor P. Debattista +4
The presence of black holes (BHs) at the centers of dwarf elliptical galaxies (dEs) has been argued both theoretically and observationally. Using archival HST/WFPC2 data, we found…
Revised bolometric corrections and interstellar extinction coefficients for the ACS and WFPC2 photometric systems
L. Girardi, J. Dalcanton, B. Williams +8
We present extensive tables of bolometric corrections and interstellar extinction coefficients for the WFPC2 and ACS (both WFC and HRC) photometric systems. They are derived from s…
Spitzer's View of Edge-on Spirals
B. W. Holwerda, R. S. de Jong, A. Seth +4
Edge-on spiral galaxies offer a unique perspective on disks. One can accurately determine the height distribution of stars and ISM and the line-of-sight integration allows for the…
