The Dual-Axis Circumstellar Environment of the Type IIn Supernova 1997eg
Jennifer L. Hoffman, Douglas C. Leonard, Ryan Chornock +3
We present multi-epoch spectral and spectropolarimetric observations of the Type IIn supernova (SN) 1997eg that indicate the presence of a flattened disk-like concentration of circ…
Transient and Highly Polarized Double-Peaked H-alpha Emission in the Seyfert 2 Nucleus of NGC 2110
Edward C. Moran, Aaron J. Barth, Michael Eracleous +1
We have discovered an extremely broad, double-peaked H-alpha emission line in the polarized flux spectrum of NGC 2110, establishing that this well-studied Seyfert 2 galaxy contains…
Serendipitous XMM-Newton discovery of a cluster of galaxies at z=0.28
Fabio Gastaldello, David A. Buote, Philip J. Humphrey +5
We report the discovery of a galaxy cluster serendipitously detected as an extended X-ray source in an offset observation of the group NGC 5044. The cluster redshift, z=0.281, dete…
A Normal Stellar Disk in the Galaxy Malin 1
A. J. Barth
Since its discovery, Malin 1 has been considered the prototype and most extreme example of the class of giant low surface brightness disk galaxies. Examination of an archival Hubbl…
