Discovery of a close pair of faint dwarf galaxies in the halo of Centaurus A
D. Crnojević, D. J. Sand, N. Caldwell +6
As part of the Panoramic Imaging Survey of Centaurus and Sculptor (PISCeS) we report the discovery of a pair of faint dwarf galaxies (CenA-MM-Dw1 and CenA-MM-Dw2) at a projected di…
Reverberation Mapping of the Kepler-Field AGN KA1858+4850
Liuyi Pei, Aaron J. Barth, Greg S. Aldering +40
KA1858+4850 is a narrow-line Seyfert 1 galaxy at redshift 0.078 and is among the brightest active galaxies monitored by the Kepler mission. We have carried out a reverberation mapp…
Extended Structure and Fate of the Nucleus in Henize 2-10
Dieu D. Nguyen, Anil C. Seth, Amy E. Reines +3
We investigate the structure and nuclear region of the black hole (BH) hosting galaxy Henize2-10. Surface brightness (SB) profiles are analyzed using Magellan/Megacam - and -…
Discovery of a new faint dwarf galaxy associated with NGC 253
D. J. Sand, D. Crnojević, J. Strader +6
We report the discovery of a new faint dwarf galaxy, which we dub Scl-MM-Dw1, at a projected distance of 65 kpc from the spiral galaxy NGC 253. The discovery results from the…
Early Observations and Analysis of the Type Ia SN 2014J in M82
G. H. Marion, D. J. Sand, E. Y. Hsiao +23
We present optical and near infrared (NIR) observations of the nearby Type Ia SN 2014J. Seventeen optical and twenty-three NIR spectra were obtained from 10 days before (10d) to…
The rise of SN2014J in the nearby galaxy M82
A. Goobar, J. Johansson, R. Amanullah +31
We report on the discovery of SN2014J in the nearby galaxy M82. Given its proximity, it offers the best opportunity to date to study a thermonuclear supernova over a wide range of…
