On the Origin of Cores in Simulated Galaxy Clusters
N. L. Mitchell, I. G. McCarthy, R. G. Bower +2
(Abridged) The thermal state of the intracluster medium results from a competition between gas cooling and heating. The heating comes from two distinct sources: gravitational heati…
Abell 851 and the Role of Starbursts in Cluster Galaxy Evolution
A. Oemler, A. Dressler, D. Kelson +5
We use extensive new observations of the very rich z ~ 0.4 cluster of galaxies A851 to examine the nature and origin of starburst galaxies in intermediate-redshift clusters. New HS…
Simultaneous H.E.S.S. and Chandra observations of Sagittarius A* during an X-ray flare
H. E. S. S. Collaboration, :, F. Aharonian
The rapidly varying (~10 minute timescale) non-thermal X-ray emission observed from Sgr A* implies that particle acceleration is occuring close to the event horizon of the supermas…
Nucleosynthetic osmium isotope anomalies in acid leachates of the Murchison meteorite
L. Reisberg, N. Dauphas, A. Luguet +3
We present osmium isotopic results obtained by sequential leaching of the Murchison meteorite, which reveal the existence of very large internal anomalies of nucleosynthetic origin…
Very high energy gamma-ray observations of the galaxy clusters Abell 496 and Abell 85 with H.E.S.S
H. E. S. S. Collaboration, :, F. Aharonian
Aims: The nearby galaxy clusters Abell 496 and Abell 85 are studied in the very high energy (VHE, E > 100 GeV) band to investigate VHE cosmic rays (CRs) in this class of objects wh…
Phase-space structure in the local dark matter distribution and its signature in direct detection experiments
Mark Vogelsberger, Amina Helmi, Volker Springel +6
We study predictions for dark matter phase-space structure near the Sun based on high-resolution simulations of six galaxy halos taken from the Aquarius Project. The local DM densi…
Testing the predictions of the cold dark matter model for the sizes, colours, morphologies and luminosities of galaxies with the SDSS
J. E. Gonzalez, C. G. Lacey, C. M. Baugh +2
The huge size and uniformity of the Sloan Digital Sky Survey makes possible an exacting test of current models of galaxy formation. We compare the predictions of the GALFORM semi-a…
Balancing the Energy Budget between Star-Formation and AGN in High Redshift Infrared Luminous Galaxies
E. J. Murphy, R. -R. Chary, D. M. Alexander +5
(abridged) We present deep Spitzer mid-infrared spectroscopy, along with 16, 24, 70, and 850um photometry, for 22 galaxies located in GOODS-N. The sample spans a redshift range of…
A New Window of Exploration in the Mass Spectrum: Strong Lensing by Galaxy Groups in the SL2S
M. Limousin, R. Cabanac, R. Gavazzi +21
The existence of strong lensing systems with Einstein radii (Re) covering the full mass spectrum, from ~1-2" (produced by galaxy scale dark matter haloes) to >10" (produced by gala…
Morphological Composition of z~0.4 groups: The site of S0 formation
D. J. Wilman, A. Oemler, J. S. Mulchaey +3
The low redshift Universe (z<~0.5) is not a dull place. Processes leading to the suppression of star formation and morphological transformation are prevalent: this is particularly…
Towards micro-arcsecond spatial resolution with Air Cherenkov Telescope arrays as optical intensity interferometers
W. J. de Wit, S. LeBohec, J. A. Hinton +3
In this poster contribution we highlight the equivalence between an Imaging Air Cherenkov Telescope (IACT) array and an Intensity Interferometer for a range of technical requiremen…
The location and kinematics of the coronal-line emitting regions in AGN
J. R. Mullaney, M. J. Ward, C. Done +2
We use the photoionisation code Cloudy to determine both the location and the kinematics of the optical forbidden, high ionisation line (hereafter, FHIL) emitting gas in the narrow…
Highly ionized gas on galaxy scales: mapping the interacting Seyfert galaxy LEDA 135736
J. Gerssen, D. J. Wilman, L. Christensen +2
We have used the VIMOS IFU to map the properties of the Seyfert 1.9 galaxy LEDA 135736. These maps reveal a number of interesting features including: an Extended Narrow Line Region…
The energy spectrum of cosmic-ray electrons at TeV energies
H. E. S. S. Collaboration, :, F. Aharonian
The very large collection area of ground-based gamma-ray telescopes gives them a substantial advantage over balloon/satellite based instruments in the detection of very-high-energy…
Extremely Red Objects in a hierarchical universe
V. Gonzalez-Perez, C. M. Baugh, C. G. Lacey +1
We analyse whether hierarchical formation models based on Lambda cold dark matter cosmology can produce enough massive red galaxies to match observations. For this purpose, we comp…
Massive, red galaxies in a hierarchical universe I. Counts of Extremely Red Objects and basic properties
V. Gonzalez-Perez, C. M. Baugh, C. G. Lacey +1
We present predictions for the abundance and nature of Extremely Red Objects (EROs) in the Lambda cold dark matter model. EROs are red, massive galaxies observed at z>= 1 and their…
