Star formation properties and dynamics of Luminous Infrared Galaxies with adaptive optics
Petri Vaisanen, Seppo Mattila, Stuart Ryder
Near infrared adaptive optics observations are crucial to be able to interpret kinematic and dynamical data and study star formation properties within the often extremely dusty int…
Discovery of the first symbiotic star in NGC6822
A. Kniazev, P. Vaisanen, P. A. Whitelock +10
We report the discovery of the first symbiotic star (V=21.6, K_S=15.8 mag) in the Local Group dwarf irregular galaxy NGC6822. This star was identified during a spectral survey of H…
The metallicity extremes of the Sagittarius dSph using SALT spectroscopy of PNe
A. Kniazev, A. Zijlstra, E. Grebel +10
In this work we present the first spectroscopic results obtained with the Southern African Large Telescope (SALT) telescope during its perfomance-verification phase. We find that t…
The polar ring galaxy AM1934-563 revisited
N. Brosch, A. Kniazev, D. Buckley +8
We report long-slit spectroscopic observations of the dust-lane polar-ring galaxy AM1934-563 obtained with the Southern African Large Telescope (SALT) during its performance-verifi…
A comparison of density structures of a star forming and a non-star-forming globule. DCld303.8-14.2 and Thumbprint Nebula
J. Kainulainen, K. Lehtinen, P. Vaisanen +2
We present a study of radial density structure of the star forming globule, DCld303.8-14.2 (DC303), and a non-star forming globule, Thumbprint Nebula (TPN), using near-infrared dat…
Faint far-infrared sources: Galaxies, clusters, or cluster galaxies
P. Vaisanen, M. Juvela, K. Mattila +1
We present results from an on-going follow-up campaign of far-infrared sources detected as part of our ISOPHOT Cosmic IR Background project. Fields have been imaged in the optical…
