Integralfield spectroscopy of galaxies

2011
This work aims to give a closer look into the properties of the Seyfert galaxy UGC 1935 which is in interaction with LEDA 212995, as well as Mrk 607 which is part of a galaxy group. Kinematic studies using absorption lines (e.g. Rupke et al., 2005) show large scale gas flows in interacting galaxies.

ISO spectroscopy of luminous infrared galaxies

Advances in Space Research, 2000
Abstract Spectroscopy from the Infrared Space Observatory ISO has for the first time provided the sensitivity to observe mid-infrared fine structure lines and PAH features in a wide range of luminous infrared galaxies. We report on observations obtained with SWS, ISOPHOT-S, and the ISOCAM CVF and show that the mid-IR spectral features are excellent ...

Integral Field Spectroscopy of Active Galaxies

Astrophysics and Space Science, 2001
Integral Field Spectroscopy techniques are ideal to study objects of complex morphology and kinematics such as the circumnuclear region of AGNs. We have obtained the stellar and ionized gas kinematics of a sample of AGNs using IFS with optical fibers. The kinematics of the stellar component seems to correspond to a rotating disk with some peculiarities.

Spectroscopy of selected Coma cluster galaxies.

Publications of the Astronomical Society of the Pacific, 1975
New determinations of redshift are given for 14 galaxies in the direction of the Coma cluster. Nine of these galaxies have not been studied spectroscopically before. The comparison of the new redshifts of the remaining five galaxies with those published previously is good with (Voew - Void) = -29 km sec-1.

Integral-Field Spectroscopy of High-Redshift Galaxies: Implications for Early Galaxy Evolution

2006
Several lines of evidence suggest that the most active phase of galaxy evolution, especially in the most massive systems, was largely completed by $z\sim 1$. This results, e.g., from the observation that the most massive galaxies at low redshift have very old stellar populations ($\sim 10$ Gyr) and very little gas to fuel subsequent star formation ...

Near Infrared Spectroscopy of LINER Galaxies

1996
This thesis reports the design and operation of a new near infrared spectrograph for the 5 m Hale telescope and its use to observe a sample of LINER galaxies. The spectrograph operates between 1 and 5 microns using existing infrared array cameras. It has two long-slit spectroscopy modes yielding resolutions (λ/Δλ) of ~850 and ~3300 with a 0.75" wide ...

Integral Field Spectroscopy of Seyfert Galaxies

Publications of the Astronomical Society of the Pacific, 2001
The present work is based on a spectroscopically selected sample of Seyfert galaxies and consists of the observation, reduction, and analysis of three-dimensional data, obtained through the MPFS, the integral field spectrograph designed and developed by the scientists of the Special Astrophysical Observatory (Russia) for the 6 m telescope.

X-Ray Spectroscopy of Galaxy Clusters

1994
In the past few years, the results obtained with the X-ray satellites EXOSAT and GlNGA, combined with more ancient data from the EINSTEIN satellite (SSS and MPC), have greatly increased our knowledge of the spectroscopic properties of the intra-cluster medium.
