Metallicity Mapping with gri Photometry: The Virgo Overdensity and the Halos of the Galaxy
Timothy C. Beers, Deokkeun An, Jennifer A. Johnson +7
We describe the methodology required for estimation of photometric estimates of metallicity based on the SDSS gri passbands, which can be used to probe the properties of main-seque…
Multi-generation massive star-formation in NGC3576
C. R. Purcell, V. Minier, S. N. Longmore +7
Recent 1.2-mm continuum observations have shown the giant HII region NGC3576 to be embedded in the centre of an extended filamentary dust-cloud. The bulk of the filament away from…
Dark Matter Direct Detection Signals inferred from a Cosmological N-body Simulation with Baryons
F. -S. Ling, E. Nezri, E. Athanassoula +1
We extract at redshift z=0 a Milky Way sized object including gas, stars and dark matter (DM) from a recent, high-resolution cosmological N-body simulation with baryons. Its resolu…
The IMF of stellar clusters: effects of accretion and feedback
Sami Dib, Mohsen Shadmehri, Paolo Padoan +3
(abridged) We develop a model which describes the coevolution of the mass function of dense cores and of the IMF in a protocluster clump. In the model, cores injected in the clump…
Massive Clusters in the Inner Regions of NGC 1365: Cluster Formation and Gas Dynamics in Galactic Bars
Bruce G. Elmegreen, Emmanuel Galliano, Danielle Alloin
Cluster formation and gas dynamics in the central regions of barred galaxies are not well understood. This paper reviews the environment of three 10^7 Msun clusters near the inner…
Evidence of triggered star formation in G327.3-0.6. Dust-continuum mapping of an infrared dark cloud with P-ArTéMiS
V. Minier, Ph. André, P. Bergman +17
Aims. Expanding HII regions and propagating shocks are common in the environment of young high-mass star-forming complexes. They can compress a pre-existing molecular cloud and tri…
Simultaneous Multi-Wavelength Observations of Sgr A* during 2007 April 1-11
F. Yusef-Zadeh, H. Bushouse, M. Wardle +18
We report the detection of variable emission from Sgr A* in almost all wavelength bands (i.e. centimeter, millimeter, submillimeter, near-IR and X-rays) during a multi-wavelength o…
A Photometric Metallicity Estimate of the Virgo Stellar Overdensity
Deokkeun An, Jennifer A. Johnson, Timothy C. Beers +6
We determine photometric metal abundance estimates for individual main-sequence stars in the Virgo Overdensity (VOD), which covers almost 1000 deg^2 on the sky, based on a calibrat…
Dynamical masses of early-type galaxies at z~2: Are they truly superdense?
Michele Cappellari, S. di Serego Alighieri, A. Cimatti +11
We measured stellar velocity dispersions sigma and dynamical masses of 9 massive (M~10^11 Msun) early-type galaxies (ETG) from the GMASS sample at redshift 1.4<z<2.0. The sigma are…
Spectrum and variability of the Galactic Center VHE gamma-ray source HESS J1745-290
H. E. S. S. collaboration, :, F. Aharonian
A detailed study of the spectrum and variability of the source HESS J1745-290 in the Galactic Center (GC) region using new data from the H.E.S.S. array of Cherenkov telescopes is p…
Evidence for X-ray synchrotron emission from simultaneous mid-IR to X-ray observations of a strong Sgr A* flare
K. Dodds-Eden, D. Porquet, G. Trap +22
This paper reports measurements of Sgr A* made with NACO in L' -band (3.80 um), Ks-band (2.12 um) and H-band (1.66 um) and with VISIR in N-band (11.88 um) at the ESO VLT, as well a…
The orientations of molecular clouds in the outer Galaxy: Evidence for the scale of the turbulence driver ?
Sami Dib, C. Jakob Walcher, Mark Heyer +2
Supernova explosions inject a considerable amount of energy into the interstellar medium (ISM) in regions with high to moderate star formation rates. In order to assess whether the…
A polycrystalline graphite model for the 2175 Angstrom interstellar extinction band
Robert J. Papoular, Renaud Papoular
A random, hydrogen-free, assembly of microscopic sp2 carbon chips, forming a macroscopically homogeneous and isotropic solid, is proposed as a model carrier for the UV interstellar…
The energetic environment and the dense interstellar medium in ULIRGs
O. Vega, M. S. Clemens, A. Bressan +3
We fit the near-infrared to radio spectral energy distributions of a sample of 30 luminous and ultra-luminous infrared galaxies with models that include both starburst and AGN comp…
Physical Conditions in the Ionized Gas of 30 Doradus
R. Indebetouw, G. E. de Messières, S. Madden +13
We present a mid-infrared spectroscopic data cube of the central part of 30 Doradus, observed with Spitzer's IRS and MIPS/SED mode. Aromatic dust emission features and emission lin…
A systematic fitting scheme for caustic-crossing microlensing events
N. Kains, A. Cassan, K. Horne +42
We outline a method for fitting binary-lens caustic-crossing microlensing events based on the alternative model parameterisation proposed and detailed in Cassan (2008). As an illus…
Disk formation and the origin of clumpy galaxies at high redshift
Oscar Agertz, Romain Teyssier, Ben Moore
Observations of high redshift galaxies have revealed a multitude of large clumpy rapidly star-forming galaxies. Their formation scenario and their link to present day spirals is st…
