Adaptive optics observations of luminous infrared galaxies II . Imaging
We present adaptive optics observations of the Luminous Infrared Galaxy, Arp 299. This merging galaxy (NGC 3690) is the site of a very powerful starburst activity. Very high angular resolution observations at 2.2μm reveal many superclusters of newly formed stars. Those clusters feature intrinsic luminosities and surface densities well above the figures generally found in the Local Cluster, poin...
متن کاملNear-infrared Adaptive Optics Imaging of High-redshift Quasars
The properties of high-redshift quasar host galaxies are studied in order to investigate the connection between galaxy evolution, nuclear activity, and the formation of supermassive black holes. We combine new near-IR observations of three high-redshift quasars (2 < z < 3), obtained at the ESOVery Large Telescope equipped with adaptive optics, with selected data from the literature. For the thr...
متن کاملNear-Infrared Adaptive Optics Imaging of QSO Host Galaxies
We report near-infrared (primarily H-band) adaptive optics (AO) imaging with the Gemini-N and Subaru Telescopes, of a representative sample of 32 nearby (z < 0.3) QSOs selected from the Palomar-Green (PG) Bright Quasar Survey (BQS), in order to investigate the properties of the host galaxies. Twodimensional modeling and visual inspection of the images shows that ∼36% of the hosts are elliptical...
متن کاملThe Initial Mass Function of the Massive Star-forming Region Ngc 3603 from Near-infrared Adaptive Optics Observations
We study the initial mass function (IMF) of one of the most massive Galactic star-forming regions NGC 3603 to answer a fundamental question in current astrophysics: is the IMF universal, or does it vary? Using our very deep, high angular resolution JHKSL ′ images obtained with NAOS-CONICA at the VLT at ESO, we have successfully revealed the stellar population down to the subsolar mass range in ...
متن کاملVERITAS Observations of Magnetars
Magnetars are rotating neutron stars with extremely strong magnetic fields (∼ 10−10G). Xray and soft gamma-ray observations have revealed the existence of non-thermal particle populations which may suggest emission of very high energy photons. VERITAS, an array of four 12m imaging atmospheric Cherenkov telescopes, is designed to observe gamma-ray emission between 100 GeV and 30 TeV. Here we pre...
