Large-scale horizontal flows in the solar photosphere III: Effects on filament destabilization

Th. Roudier, M. Svanda, N. Meunier +7

We study the influence of large-scale photospheric motions on the estabilization of an eruptive filament, observed on October 6, 7, and 8, 2004, as part of an international observi…

Comments on the ERA-2005 numerical theory of Earth rotation

P. M. Mathews, N. Capitaine, V. Dehant

Two papers recently published in Celestial Mechanics (Krasinsky 2006, and Krasinsky and Vasilyev 2006) have presented a model for Earth-rotation variations, called ERA-2005, based…

A Spectacular VHE Gamma-Ray Outburst from PKS 2155-304 in 2006

W. Benbow, C. Boisson, L. Costamante +10

Since 2002 the VHE (>100 GeV) gamma-ray flux of the high-frequency peaked BL Lac PKS 2155-304 has been monitored with the High Energy Stereoscopic System (HESS). An extreme gamma-r…

Multi-wavelength Observations of PG 1553+113 with HESS

HESS Collaboration, W. Benbow, C. Boisson +2

Very high energy (VHE; >100 GeV) gamma-ray observations of PG 1553+113 were made with the High Energy Stereoscopic System (HESS) in 2005 and 2006. A strong signal, ~10 standard dev…

Iron lines from transient and persisting hot spots on AGN accretion disks

R. W. Goosmann, M. Mouchet, B. Czerny +4

[abridged] We model the X-ray reprocessing from a strong co-rotating flare above an accretion disk in active galactic nuclei. We explore the horizontal structure and evolution of t…

Tidal tails around globular clusters

M. Montuori, R. Capuzzo-Dolcetta, P. Di Matteo +1

We present the results of detailed N-body simulations of clusters moving in a realistic Milky Way (MW) potential. The strong interaction with the bulge and the disk of the Galaxy l…

The Physical Properties of LBGs at z>5: Outflows and the "pre-enrichment problem"

M. D. Lehnert, M. Bremer, A. Verma +2

We discuss the properties of Lyman Break galaxies (LBGs) at z>5 as determined from disparate fields covering approximately 500 sq. arcmin. While the broad characteristics of the LB…

On magnetic instabilities and dynamo action in stellar radiation zones

J. -P. Zahn, A. S. Brun, S. Mathis

We examine the MHD instabilities arising in the radiation zone of a differentially rotating star, in which a poloidal field of fossil origin is sheared into a toroidal field. We fo…

Discovery of Interstellar Propylene (CH_2CHCH_3): Missing Links in Interstellar Gas-Phase Chemistry

N. Marcelino, J. Cernicharo, M. Agundez +5

We report the discovery of propylene (also called propene, CH_2CHCH_3) with the IRAM 30-m radio telescope toward the dark cloud TMC-1. Propylene is the most saturated hydrocarbon e…

C IV absorption in damped and sub-damped Lyman-alpha systems: correlations with metallicity and implications for galactic winds at z~2-3

Andrew J. Fox, Cédric Ledoux, Patrick Petitjean +1

We present a study of C IV absorption in a sample of 63 damped Lyman-alpha (DLA) systems and 11 sub-DLAs in the redshift range 1.75<z_abs<3.61, using a dataset of high-resolution (…

Resolving the innermost parsec of Centaurus A at mid-infrared wavelengths

K. Meisenheimer, K. R. W. Tristram, W. Jaffe +11

We report the results of interferometric observations of Centaurus A with the MID-infrared Interferometer (MIDI) at ESO's VLTI telescope array. The interferometric measurements are…

21-cm synthesis observations of VIRGOHI 21 - a possible dark galaxy in the Virgo Cluster

Robert Minchin, Jonathan Davies, Michael Disney +10

Many observations indicate that dark matter dominates the extra-galactic Universe, yet no totally dark structure of galactic proportions has ever been convincingly identified. Prev…

Unveiling the broad band X-ray continuum and iron line complex in Mkr 841

P. O. Petrucci, G. Ponti, G. Matt +7

Mkr 841 is a bright Seyfert 1 galaxy known to harbor a strong soft excess and a variable K iron line. It has been observed during 3 different periods by XMM for a total cumulate…

The effects of spatially distributed ionisation sources on the temperature structure of HII region

B. Ercolano, N. Bastian, G. Stasinska

Spatially resolved studies of star forming regions show that the assumption of spherical geometry is not realistic in most cases, with a major complication posed by the gas being i…

EROs found behind lensing clusters. II. Stellar populations and dust properties of optical dropout EROs and comparison with related objects

D. Schaerer, A. Hempel, E. Egami +6

We determine the nature, redshift, stellar populations and dust properties of optically faint or non-detected extremely red objects (ERO) found from our survey of the lensing clust…
