We probe the dust extinction through the foreground disk of the overlapping galaxy pair UGC 5041 by analyzing B,I, and H band images. The inclined foreground disk of this infrared-selected pair is...
Lopsidedness in Early Type Disk Galaxies (1998)
Rudnick, Gregory, Rix, Hans-Walter
We quantify the mean asymmetry of 54 face-on, early type disk galaxies (S0 to Sab) using the amplitude of the m=1 azimuthal Fourier component of the R-band surface brightness. We find that the median...
Maximal Disks and the Tully-Fisher Relation (1997)
Courteau, Stephane, Rix, Hans-Walter
We show that for luminous, non-barred, high-surface brightness (HSB) spirals the Tully-Fisher (TF) relation residuals can be used to estimate the relative mass contributions of the stellar disk and...

Dynamical Modeling of Velocity Profiles: The Dark Halo around the . . . (1997)
Hans-Walter Rix, Nicolas Cretton, Roeland P. Der
We describe a powerful technique to model and interpret the stellar line-of-sight velocity profiles of galaxies. It is based on Schwarzschild's approach to build fully general dynamical models....

A survey for large image-separation lensed quasars (1996)
Maoz, Dan, Rix, Hans-Walter, Gal-Yam, Avishay, Gould, Andrew
The statistics of gravitationally lensed quasars with multiple images in the 0.1''-7'' range have been measured in various surveys. Little is known, however, about lensed-quasar statistics at larger...
Lopsided Spiral Galaxies and a Limit on the Galaxy Accretion Rate (1996)
Zaritsky, Dennis, Rix, Hans-Walter
We present a measurement of lopsidedness for the stellar disks of 60 field spiral galaxies in terms of the azimuthal m=1 Fourier amplitude, A_1, of the stellar light. We conjecture that this...
An Atlas of Hubble Space Telescope Ultraviolet Images of Nearby Galaxies (1996)
Maoz, Dan, Filippenko, Alexei V., Ho, Luis C., Macchetto, F. Duccio, Rix, Hans-Walter, Schneider, Donald P.
We present an atlas of UV ($\sim 2300$ \AA) images, obtained with the Hubble Space Telescope (HST) Faint Object Camera, of the central $22''\times 22''$ of 110 galaxies. The observed galaxies are an...
Hubble Space Telescope Ultraviolet Images of Five Circumnuclear Star-Forming Rings (1996)
Maoz, Dan, Barth, Aaron J., Sternberg, Amiel, Filippenko, Alexei V., Ho, Luis C., Macchetto, F. Duccio, ...
We present UV (2300 Ang) images, obtained with the HST Faint Object Camera, of the central 20'' of five galaxies containing circumnuclear star-forming rings. The five galaxies are from a well-defined...
Quantitative analysis of galaxy-galaxy lensing (1996)
Schneider, Peter, Rix, Hans-Walter
In this paper we explore a quantitative and efficient method to constrain the halo properties of distant galaxy populations through ``galaxy--galaxy" lensing and show that the mean masses and sizes...
NON-AXISYMMETRIC STRUCTURES IN THE STELLAR DISKS OF GALAXIES (1995)
Rix, Hans-Walter, Zaritsky, Dennis
We study the azimuthal structure of the stellar disks of 18 face-on spiral galaxies, using K-band photometry to trace the stellar surface mass density. Assuming the disks are co-planar, we...
CONSTRAINTS ON THE OPACITY OF SPIRAL DISKS FROM NEAR-INFRARED OBSERVATIONS (1995)
In this paper I review how near-infrared (NIR) observations can constrain the opacity of spiral disks. Basic considerations show that NIR photometry provides a powerful probe of the optical depths in...
THE SHAPES OF DARK HALOS (1995)
The shapes of dark halos (e.g. spherical, oblate or triaxial) provide important clues to the formation history of the halos, to their baryon content and to the nature of the dark matter. The halo...
Detection of Compact Ultraviolet Nuclear Emission in LINER Galaxies (1994)
Maoz, Dan, Filippenko, Alexei V., Ho, Luis C., Rix, Hans-Walter, Bahcall, John N., Schneider, Donald P., ...
Low-ionization nuclear emission-line regions (LINERs), which exist in a large fraction of galaxies, may be the least luminous manifestation of quasar activity. The nature of LINERs has, however,...

Rix, Hans-Walter, Rieke, Marcia J.
We present optical and IR surface photometry of M51 (NGC~5194) at B~V~R~I~J~K and CO$(2.3\mu )$. These data are used to establish whether K-band ($2.2\mu$) images of spiral galaxies provide reliable...
The past and the future fate of the universe and the formation of structure in it
The history and the ultimate future fate of the universe as a whole depend on how much the expansion of the universe is decelerated by its own mass. In particular, whether the expansion of the...
