Galaxy Harassment—Interactions for the 90s [PDF]
Symposium - International Astronomical Union, 1999 The origin of the Hubble sequence remains a long-standing puzzle in astronomy. Giant galaxies range from slowly-rotating dense ellipticals to thin late-type spiral disks. At the faint end, there are two distinct classes of “ellipticals/spheroids” that are easily separated in plots of nearly any two of their properties, such as central surface ...

Characterizing the Molecular Gas in Infrared Bright Galaxies with CARMA
The Astrophysical JournalWe present the CO(1–0) maps of 28 infrared-bright galaxies from the Great Observatories All-Sky Luminous Infrared Galaxy Survey (GOALS) taken with the Combined Array for Research in Millimeter Astronomy (CARMA).

XMM-Newton observations of the interacting galaxy pairs NGC 7771/0 and NGC 2342/1 [PDF]
, 2004 We present XMM‐Newton X-ray observations of the interacting galaxy pairs NGC 7771/7770 and NGC 2342/2341. In NGC 7771, for the first time we are able to resolve the X-ray emission into a bright central source plus two bright (L X > 10 40 erg s −1 ...

The colour of the narrow line Sy1-blazar 0324+3410
, 2008 Aims. We investigate the properties of the host galaxy of the blazar J0324+3410 (B2 0321+33) by the analysis of B and R images obtained with the NOT under good photometric conditions.

Ongoing Mass Transfer in the Interacting Galaxy Pair NGC 1409/1410 [PDF]
, 2000 I present two-band Hubble Space Telescope (HST) STIS imaging and WIYN spectral mapping of ongoing mass transfer in the interacting galaxy pair NGC 1409/1410 (where NGC 1410 is the Seyfert galaxy also cataloged as III Zw 55).

The frequency and properties of young tidal dwarf galaxies in nearby gas-rich groups
, 2016 We present high-resolution Giant Metrewave Radio Telescope (GMRT) HI observations and deep Canada-France-Hawaii Telescope (CFHT) optical imaging of two galaxy groups: NGC 4725/47 and NGC 3166/9.

A CATALOG OF BRIGHT STAR CLUSTERS IN THE INTERACTING GALAXY M51 [PDF]
, 2007 We present a catalog of star clusters with VF555W < 23 mag detected in the interacting spiral galaxy M51 system based on mosaic images taken with the Hubble Space Telescope Advanced Camera for Surveys by the Hubble Heritage Team.

Energy Evolution in the Progenitor of Galaxy Shells: A Semi-analytical Model
The Astrophysical JournalThe stellar shells surrounding an elliptical galaxy, as remnants of a dwarf galaxy disrupted during merging, reveal the distribution of energy and angular momentum of the progenitor dwarf galaxy. We develop a semi-analytical model to describe the changes

Galaxies, 2018 The cold dark matter (CDM) paradigm successfully explains the cosmic structure over an enormous span of redshifts. However, it fails when probing the innermost regions of dark matter halos and the properties of the Milky Way’s dwarf galaxy satellites ...
