Distances to Galactic methanol masers
K. L. J. Rygl, A. Brunthaler, K. M. Menten +2
We present the first EVN parallax measurements of 6.7 GHz methanol masers in star forming regions of the Galaxy. The 6.7 GHz methanol maser transition is a very valuable astrometri…
The SAURON project - XI. Stellar Populations from Absorption Line Strength Maps of 24 Early-Type Spirals
Reynier F. Peletier, Jesus Falcon-Barroso, Roland Bacon +10
We present absorption line strength maps of a sample of 24 representative early-type spiral galaxies, mostly of type Sa, obtained as part of the SAURON survey of nearby galaxies us…
The SAURON project -- IX. A kinematic classification for early-type galaxies
Eric Emsellem, Michele Cappellari, Davor Krajnovic +10
2D stellar kinematics of 48 representative E and S0 galaxies obtained with the SAURON IFS reveal that early-type galaxies appear in two broad flavours, depending on whether they ex…
A SCUBA/Spitzer Investigation of the Far Infra-Red Extragalactic Background
S. Dye, S. A. Eales, M. L. N. Ashby +5
We have measured the contribution of submillimeter and mid-infrared sources to the extragalactic background radiation at 70 and 160um. Specifically, we have stacked flux in 70 and…
Simulating Cosmic Reionization at Large Scales II: the 21-cm Emission Features and Statistical Signals
Garrelt Mellema, Ilian T. Iliev, Ue-Li Pen +1
We present detailed predictions for the redshifted 21cm signal from the epoch of reionization. These predictions are obtained from radiative transfer calculations on the results of…
First evidence for a spatially resolved disk structure around the Herbig Ae star R CrA
S. Correia, R. Koehler, G. Meeus +1
We present mid-infrared interferometric observations of the Herbig Ae star R CrA obtained with MIDI at the VLTI using several projected baselines in the UT2-UT3 configuration. The…
A Multiplicity Survey of the Rho Ophiuchi Molecular Clouds
Thorsten Ratzka, Rainer Koehler, Christoph Leinert
We present a volume-limited multiplicity survey with magnitude cutoff (K =< 10.5 mag) of 158 young stellar objects located within or in the vicinity of the Rho Ophiuchi Dark Cloud.…
Deep SAURON Spectral-Imaging of the diffuse Lyman-alpha halo LAB1 in SSA22
Richard Bower, S. L. Morris, R. Bacon +6
We have used the SAURON panoramic integral field spectrograph to study the structure of the Ly-alpha emission-line halo, LAB1, surrounding the sub-millimeter galaxy SMM J221726+001…
High-Energy Radiation Probes of Protostellar Envelopes
P. Stäuber, A. O. Benz, S. D. Doty +2
We present observations of molecular high-energy radiation probes and report the first detections of CO+ toward W3 IRS5, a source containing ultracompact HII regions. UV radiation…
On the origin of the O and B-type stars with high velocities II Runaway stars and pulsars ejected from the nearby young stellar groups
R. Hoogerwerf, J. H. J. de Bruijne, P. T. de Zeeuw
We use milli-arcsecond accuracy astrometry (proper motions and parallaxes) from Hipparcos and from radio observations to retrace the orbits of 56 runaway stars and nine compact obj…
An accelerated Monte Carlo method to solve two-dimensional radiative transfer and molecular excitation
Michiel R. Hogerheijde, Floris F. S. van der Tak
We present a numerical method and computer code to calculate the radiative transfer and excitation of molecular lines. Formulating the Monte Carlo method from the viewpoint of cell…
The Elusive Active Nucleus of NGC 4945
A. Marconi, E. Oliva, P. P. van der Werf +4
We present new HST NICMOS observations of NGC 4945, a starburst galaxy hosting a highly obscured active nucleus that is one of the brightest extragalactic sources at 100 keV. The H…
MHD Turbulence in Star-Forming Clouds
Mordecai-Mark Mac Low, Ralf Klessen, Fabian Heitsch
We review how supersonic turbulence can both prevent and promote the collapse of molecular clouds into stars. First we show that decaying turbulence cannot significantly delay coll…
Giant and `double-double' radio galaxies: Implications for the evolution of powerful radio sources and the IGM
A. P. Schoenmakers, A. G. de Bruyn, H. J. A. Röttgering +3
Giant radio sources form the linear size extreme of the extra-galactic radio source population. Using the WENSS survey, we have selected a complete sample of these sources. We have…
HST Snapshot Survey of 3CR Quasars: The Data
Matthew D. Lehnert, George K. Miley, William B. Sparks +6
We present images taken with the Wide Field Planetary Camera (WFPC-2) on the Hubble Space Telescope of 43 quasars selected from the 3CR radio catalog. The redshift range of the tar…
OB Associations
Anthony G. A. Brown, A. Blaauw, R. Hoogerwerf +2
Since the previous (1990) edition of this meeting enormous progress in the field of OB associations has been made. Data from X-ray satellites have greatly advanced the study of the…
Soft X-rays from High-Velocity Clouds
J. Kerp, P. M. W. Kalberla, M. J. Freyberg +2
The ROSAT mission gave us the unique possibility to study the galactic interstellar medium by ``shadowing'' observations on arcmin angular resolution level. The high sensitivity of…
