Extragalactic Stellar Tidal Streams in the Dark Energy Survey

Juan Miro-Carretero, David Martinez-Delgado, Maria A. Gomez-Flechoso +7

Stellar tidal streams are a key tracer of galaxy evolution and have the potential to provide an indirect means for tracing dark matter. For the Local Group, many diffuse substructu…

Stellar Population Properties in the Stellar Streams Around SPRC047

Seppo Laine, David Martınez-Delgado, Kristi A. Webb +5

We have investigated the properties (e.g., age, metallicity) of the stellar populations of a ring-like tidal stellar stream (or streams) around the edge-on galaxy SPRC047 (z = 0.03…

Optimizing Roman's High Latitude Wide Area Survey for Low Surface Brightness Astronomy

Mireia Montes, Francesca Annibali, Michele Bellazzini +20

One of the last remaining frontiers in optical/near-infrared observational astronomy is the low surface brightness regime (LSB, V-band surface brightness, 27 AB mag/arcsec$^…

Morphological Parameters of Spitzer Survey of Stellar Structure in Galaxies (S4G)

B. W. Holwerda, J-C. Munoz-Mateos, S. Comeron +21

The morphology of galaxies can be quantified to some degree using a set of scale-invariant parameters. Concentration (C), Asymmetry (A), Smoothness (S), the Gini index (G), relativ…

Evolution and Impact of Bars over the Last Eight Billion Years: Early Results from GEMS

S. Jogee, F. D. Barazza, H. -W. Rix +24

Bars drive the dynamical evolution of disk galaxies by redistributing mass and angular momentum, and they are ubiquitous in present-day spirals. Early studies of the Hubble Deep Fi…

Hubble Space Telescope Imaging of Brightest Cluster Galaxies

Seppo Laine, Roeland P. van der Marel, Tod R. Lauer +3

We used the HST WFPC2 to obtain I-band images of the centers of 81 brightest cluster galaxies (BCGs), drawn from a volume-limited sample of nearby BCGs. The images show a rich vari…

Circumnuclear regions in barred spiral galaxies II. Relations to host galaxies

J. H. Knapen, D. Perez-Ramirez, S. Laine

We present optical broad- and narrow-band imaging of a sample of a dozen barred galaxies. These images are analyzed in conjunction with our previously published near-infrared imagi…

Galaxies with a Central Minimum in Stellar Luminosity Density

Tod R. Lauer, Karl Gebhardt, Douglas Richstone +15

We used HST WFPC2 images to identify six early-type galaxies with surface- brightness profiles that decrease inward over a limited range of radii near their centers. The implied lu…

Nested and Single Bars in Seyfert and Non-Seyfert Galaxies

Seppo Laine, Isaac Shlosman, Johan H. Knapen +1

We analyze the observed properties of nested and single stellar bar systems in disk galaxies. The 112 galaxies in our sample comprise the largest matched Seyfert vs. non-Seyfert sa…

Circumnuclear kinematics in NGC 5248: the origin of nuclear spiral arms

S. Laine, J. H. Knapen, D. Perez-Ramirez +2

We present for the first time a two-dimensional velocity field of the central region of the grand-design spiral galaxy NGC 5248, at 0.9 arcsec spatial resolution. The H-alpha veloc…
