A view of the solar neighbourhood: the local population of planetary nebulae and their mimics
the solar neighbourhood the local population
2011/1/10
We have, for the first time, compiled a nearly complete census of planetary nebulae (PNe) centred on the Sun. Our goal is the generation of an unbiased volume-limited sample, in order to answer some l...
Aim of this work is a broad-band study with INTEGRAL, Swift and XMM-Newton satellites of a sample of 9 blazars (7 FSRQ and 2 BL Lac) with redshift up to about 4. The spectral analysis has shown clear ...
The XMM-Newton survey of the Small Magellanic Cloud: A new X-ray view of the symbiotic binary SMC3
The XMM-Newton survey the Small Magellanic Cloud
2011/1/11
The XMM-Newton survey of the Small Magellanic Cloud (SMC) was performed to study the population of X-ray sources in this neighbouring galaxy. During one of the observations, the symbiotic binary SMC3 ...
Detailed Radio View on Two Stellar Explosions and Their Host Galaxy: XRF080109/SN2008D and SN2007uy in NGC2770
Gamma rays bursts
2010/11/15
The galaxy NGC 2770 hosted two core-collapse supernova explosions, SN2008D and SN2007uy,within 10 days of each other and 9 years after the first supernova of the same type, SN1999eh, was
found in tha...
The Murmur of The Hidden Monster: Chandra's Decadal View of The Super-massive Black Hole in M31
galaxies individual (M 31) – galaxies nuclei – X-rays galaxies
2010/11/11
The Andromeda galaxy (M31) hosts a central super-massive black hole (SMBH), known as M31∗, which is remarkable for its mass (108 M⊙) and extreme radiative quiescence. Over the past decade, the ...
High-resolution spectroscopic view of planet formation sites
planetary systems protoplanetary disks hydrodynamics line pro les
2010/11/15
Theories of planet formation predict the birth of giant planets in the inner, dense, and
gas-rich regions of the circumstellar disks around young stars. These are the regions from which strong CO emi...
New Panoramic View of $^{12}$CO and 1.1 mm Continuum Emission in the Orion A Molecular Cloud. I. Survey Overview and Possible External Triggers of Star Formation
Galaxy Astrophysics (astro-ph.GA)
2011/1/6
We present new, wide and deep images in the 1.1 mm continuum and the $^{12}$CO ($J$=1-0) emission toward the northern part of the Orion A Giant Molecular Cloud (Orion-A GMC). The 1.1 mm data were take...
Nearby early-type galaxies with ionized gas VI. The Spitzer-IRS view
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/29
We present low resolution Spitzer-IRS spectra of 40 ETGs, selected from a sample of 65 ETGs showing emission lines in their optical spectra. We homogeneously extract the mid-infrared (MIR) spectra, an...
Observations of dusty torii and compact disks around evolved stars: the high spatial resolution IR view
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/24
The recent high angular resolution observations have shown that the transition between a globally symmetrical giant and a source surrounded by a spatially complex environment occurs relatively early, ...
The far-infrared view of M87 as seen by the Herschel Space Observatory
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/24
The origin of the far-infrared emission from the nearby radio galaxy M87 remains a matter of debate. Some studies find evidence of a far-infrared excess due to thermal dust emission, whereas others pr...
A closer view of the radio-FIR correlation: disentangling the contributions of star formation and AGN activity
Galaxy Astrophysics (astro-ph.GA)
2010/12/23
We extend the Unified Radio Catalog, a catalog of sources detected by various (NVSS, FIRST, WENSS, GB6) radio surveys, and SDSS, to IR wavelengths by matching it to the IRAS Point and Faint Source cat...
A Joint Chandra and XMM-Newton View of Abell 3158: Massive Off-Centre Cool Gas Clump As A Robust Diagnostic of Merger Stage
XMM-Newton Massive Off-Centre Cool Gas Clump Abell 3158
2010/3/8
By analysing the Chandra and XMM-Newton archived data of the nearby galaxy cluster Abell 3158, which was reported to possess a relatively regular, relaxed morphology in the X-ray band in previous work...
