The star formation history of early-type galaxies in the fornax cluster [PDF]
, 1998 We have measured central line strengths and line-strength gradients for a complete sample of early-type galaxies in the Fornax cluster, comprising 11 elliptical and 11 lenticular galaxies, more luminous than M(_B) = -17.

H i Gas and Star Formation in Major Galaxy Pairs from the FAST All Sky H i Survey (FASHI)
The Astrophysical JournalAtomic hydrogen (H i ) plays a fundamental role in fueling star formation in galaxies. However, the behavior of H i gas in interacting systems, particularly galaxy pairs, remains elusive.

Low luminosity elliptical galaxies [PDF]
, 1998 Long-slit spectra for the photometric axes of a sample of 14 elliptical galaxies, predominantly low-luminosity ellipticals, in the Virgo cluster and in nearby groups, are studied to investigate the galaxy kinematical structure and stellar evolutionary ...

Line-strength indices and velocity dispersions for 148 early-type galaxies in different environments [PDF]
, 2002 We have derived high quality line-strength indices and velocity dispersions for a sample of 148 early-type galaxies in different environments. The wavelength region covered by the observations ($\lambda \simeq 4600$ to 6600 Å) includes the Lick/IDS ...

Influence of Dynamical Friction on the Unstable Manifolds of Lagrange Points in Barred Galaxies
Astronomische Nachrichten, EarlyView.ABSTRACT Some time ago the idea has been proposed that rings and spirals in barred galaxies are shaped by the unstable manifolds of the Lagrange points sitting near the ends of the bar. The topic of the present article is an investigation of whether the numerical support for this suggestion can be improved by the inclusion of dynamical friction into ...

SAURON: Observations of E/S0/Sa galaxies
, 2002 We present results from a new and unique integral-field spectrograph, SAURON. It has a large field of view and high throughput and is primarily built for the study of stellar & gaseous kinematics and stellar populations in galaxies. Its aim is to carry out a systematic survey of the velocity fields, velocity dispersions, and line-strength ...

Direct SMBH Formation Driven by Runaway Stellar Collisions in Globally Unstable Stellar Systems
Astronomische Nachrichten, EarlyView.ABSTRACT The fueling problem addresses the ultimate fate of the reservoirs of gas and stars driven into the deepest gravitational potential wells of galaxies, thus it may contain the Universe's densest concentrations of gas and stars. This raises a key question: does the infalling material collapse directly into a supermassive black hole, or can it ...
