A view of the narrow-line region in the infrared: active galactic nuclei with resolved fine-structure lines in the Spitzer archive
narrow-line region infrared: active galactic nuclei resolved fine-structure lines
2011/10/10
We queried the Spitzer archive for high-resolution observations with the Infrared Spectrograph of optically selected active galactic nuclei (AGN) for the purpose of identifying sources with resolved f...
The relation of optical/UV and X-ray emission in low-luminosity active galactic nuclei
relation optical/UV X-ray emission low-luminosity active galactic nuclei
2011/10/9
We study the relation of optical/UV and X-ray emission in the low luminosity active galactic nuclei (LLAGNs), using a sample of 49 sources including 28 local Seyfert galaxies and 21 low-ionization nuc...
Discovery and identification of infrared counterpart candidates of four Galactic centre low mass X-ray binaries
X-rays: binaries – infrared: stars – X-rays: individuals: XTE J1637− 498, IGRJ17379− 3747, IGR J17585− 3057, GX9+1
2011/9/30
The near infrared (nIR)/optical counterparts of low mass X-ray binaries (LMXBs) are often observationally dim and reside in high source density fields which make their identification problematic; howe...
Discovery of the infrared counterpart of CXOU J174437.3-323222 in the field of IGR J17448-3232: a blazar candidate viewed through the Galactic centre?
Infrared: general – Radiation mechanisms: non-thermal – X-rays: individual
2011/9/29
We present our near infrared ESO-NTT Ks band observations of the field of IGR J17448-3232 which show no extended emission consistent with the SNR but in which we identify a new counterpart, also visib...
{\it Suzaku} observation of Galactic supernova remnant CTB 37A (G348.5+0.1)
ISM: supernova remnants− ISM:individual(CTB 37A)− X-rays
2011/9/28
We present here the results of the observation of CTB 37A obtained with the X-ray Imaging Spectrometer onboard the {\it Suzaku} satellite. The X-ray spectrum of CTB 37A is well fitted by two component...
Near-Infrared Reverberation by Dusty Clumpy Tori in Active Galactic Nuclei
Near-Infrared Reverberation Dusty Clumpy Active Galactic Nuclei
2011/9/27
According to recent models, the accretion disk and black hole in active galactic nuclei are surrounded by a clumpy torus. We investigate the NIR flux variation of the torus in response to a UV flash f...

Positions, spectral identifications, and near infrared photometry for a complete sample of RGB and AGB stars on the galactic plane towards Carina。
Rosat x-ray observations of central galactic starbursts
GALAXIES x-ray observations central galactic starbursts
2009/6/4
We present spatial and spectral results of ROSAT observations of two galax-ies: NGC 4569 and NGC 4303. Both objects are members of the Virgo Cluster andhave nearby smaller companions with which they h...
Needs and requirements for future x-ray observations of hot galactic halos
HALOS X-RAYS JETS AND OUTFLOWS
2009/6/4
Galaxies are key objects for the study of cosmology, the life cycle of matter,and stellar evolution. X-ray observations have given us a new key window intothese building blocks of the Universe, that a...
The field of Very High Energy (VHE) gamma ray astronomy
using the Atmospheric Cerenkov Technique has entered an interesting
phase with detection of various galactic and extragalactic sources. Among
