A self-consistent model of isolated neutron stars: the case of the X-ray pulsar RX J0720.4-3125

Miniutti, G.; Pons, J. A.; Pérez-Azorín, J. F. +1 more

Context: .We present a unified explanation for the observed properties of the isolated neutron star RX J0720.4-3125 by obtaining a self-consistent model that accounts simultaneously for the observed X-ray spectrum and optical excess, the pulsed fraction, the observed spectral feature around 0.3 keV, and the long-term spectral evolution.
Aims: …

Irwin, John; Shmakova, Marina

Gravitational lensing by foreground halos with masses as small as 10¹⁰ M_solar can induce observable second-order shape distortions in background galaxy images in addition to the well-known elliptical shape distortion produced by first-order shear. Furthermore, the orientation of the second-order distortions is correlated with…

Variability Study of Seyfert 2 Galaxies with XMM-Newton

DOI: 10.1086/504405 Bibcode: 2006ApJ...645..928A

Awaki, Hisamitsu; Leighly, Karen M.; Murakami, Hirokatsu +1 more

We present the results of timing analysis of XMM-Newton observations of Seyfert 2 galaxies in order to search for differences in the mean properties of Seyfert 1 galaxies and Seyfert 2 galaxies. We selected 13 Seyfert 2 galaxies from the XMM-Newton archive that have hard X-ray components in their spectra and calculated the excess variance (σ^2…

X-ray reflection in the nearby Seyfert 2 galaxy NGC 1068

DOI: 10.1111/j.1365-2966.2006.10139.x Bibcode: 2006MNRAS.368..707P

Vaughan, Simon; Pounds, Ken

We use the full broad-band XMM-Newton European Photon Imaging Camera (EPIC) data to examine the X-ray spectrum of the nearby Seyfert 2 galaxy NGC 1068, previously shown to be complex with the X-ray continuum being a sum of components reflected/scattered from cold (neutral) and warm (ionized) matter, together with associated emission-line spectra. …

On-ground characterization of Rosetta/VIRTIS-M. II. Spatial and radiometric calibrations

DOI: 10.1063/1.2360786 Bibcode: 2006RScI...77j3106F

Piccioni, G.; Capaccioni, F.; Coradini, A. +5 more

After having considered the spectral and geometrical performances of the Rosetta/VIRTIS-M experiment, we complete here the analysis by evaluating quantitatively the flat-field and radiometric responses. The purpose of this work is to retrieve the flat-field matrix necessary to homogenize the focal plane response. Moreover, the most important resul…

The 2003 October-November Fast Halo Coronal Mass Ejections and the Large-Scale Magnetic Field Structures

DOI: 10.1086/500290 Bibcode: 2006ApJ...640.1135L

Liu, Y.; Hayashi, K.

The coronal magnetic field, computed from synoptic maps of the magnetic field and a potential field source surface (PFSS) model, reveals special configurations related to the active regions that were associated with most, if not all, fast halo coronal mass ejections (CMEs) in 2003 October-November. It was shown that these active regions emerged in…

A Light Echo from Type Ia SN 1995E?

DOI: 10.1086/507826 Bibcode: 2006ApJ...652..512Q

Quinn, Jason L.; Garnavich, Peter M.; Li, Weidong +4 more

We identify a light echo candidate from Hubble Space Telescope (HST) imaging of NGC 2441, the host galaxy of the Type Ia supernova 1995E. From the echo's angular size and the estimated distance to the host galaxy, we find a distance of 207+/-35 pc between the dust and the site of the supernova. If confirmed, this echo brings the total number of ob…

X-rays from HH 210 in the Orion nebula

Grosso, N.; Kastner, J. H.; Bally, J. +3 more

We report the detection during the Chandra Orion Ultradeep Project (COUP) of two soft, constant, and faint X-ray sources associated with the Herbig-Haro object HH 210. HH 210 is located at the tip of the NNE finger of the emission line system bursting out of the BN-KL complex, northwest of the Trapezium cluster in the OMC-1 molecular cloud. Using …

The Virgo High-Resolution CO Survey: VI. Gas Dynamics and Star Formation along the Bar in NGC 4303

DOI: 10.1093/pasj/58.2.299 Bibcode: 2006PASJ...58..299K

Koda, Jin; Sofue, Yoshiaki

We present CO interferometer observations of the barred galaxy NGC 4303 (M 61). This galaxy has a strong gas concentration at the central region and prominent offset ridges at the leading sides of the bar. Sharp velocity gradients are apparent across the ridges. The brightness temperature in the ridges is low, indicating the existence of unresolve…
