Chandra Observation of the Edge-on Spiral NGC 5775: Probing the Hot Galactic Disk/Halo Connection

J. T. Li, Z. Y. Li, Q. D. Wang +2

We study the edge-on galaxy NGC 5775, utilizing a 58.2 ks {\sl Chandra} ACIS-S observation together with complementary {\sl HST} ACS, {\sl Spitzer} IRAC and other multi-wavelength…

HST/ACS Observations of Star Formation Driven Outflows in Nearby Edge-on Spiral Galaxies: Dependence of Halo Morphology on Star Formation Activity

Joern Rossa, Michael Dahlem, Ralf-Juergen Dettmar +1

(Abridged). We present new high spatial resolution narrowband imaging observations of extraplanar diffuse ionized gas (eDIG) in four late-type, actively star forming edge-on spiral…

The Toomre Sequence Revisited with HST/NICMOS: Nuclear Brightness Profiles and Colors of Interacting and Merging Galaxies

Joern Rossa, Seppo Laine, Roeland P. van der Marel +4

We discuss the near-infrared properties of the nuclei in the 11 merging galaxies of the Toomre sequence, based on high spatial resolution J, H, and K imaging data using NICMOS onbo…

Nuclear Star Clusters (Nuclei) in Spiral Galaxies and Connection to Supermassive Black Holes

Roeland P. van der Marel, Joern Rossa, Carl Jakob Walcher +4

HST observations have revealed that compact sources exist at the centers of many, maybe even most, galaxies across the Hubble sequence. These sources are called "nuclei" or also "n…

The morphology of minor axis gaseous outflows in edge-on Seyfert galaxies

T. P. Robitaille, J. Rossa, D. J. Bomans +1

(Abridged) Spiral galaxies often have extended outflows that permeate beyond the region of the disk. Such outflows have been seen both in starburst galaxies, actively star forming…

HST/STIS Spectra of Nuclear Star Clusters in Spiral Galaxies: Dependence of Age and Mass On Hubble Type

Joern Rossa, Roeland P. van der Marel, Torsten Boeker +5

(Abridged) We study the nuclear star clusters in spiral galaxies of various Hubble types using spectra obtained with STIS on-board HST. We observed the nuclear clusters in 40 galax…
