VLT-FORS2 optical imaging and spectroscopy of 9 luminous type 2 AGN at 0.3<z<0.6: I. Ionized gas nebulae
A. Humphrey, M. Villar-Martín, C. Ramos Almeida +4
We present optical imaging and long slit spectroscopic observations of 9 luminous type 2 AGNs within the redshift range 0.3<z<0.6 based on VLT-FORS2 data. Most objects (6/9) are hi…
An extremely young massive clump forming by gravitational collapse in a primordial galaxy
A. Zanella, E. Daddi, E. Le Floc'h +9
When the cosmic star formation history peaks (z ~ 2), galaxies vigorously fed by cosmic reservoirs are gas dominated and contain massive star-forming clumps, thought to form by vio…
Multiscale nature of the dissipation range in gyrokinetic simulations of Alfvénic turbulence
D. Told, F. Jenko, J. M. TenBarge +2
Nonlinear energy transfer and dissipation in Alfvén wave turbulence are analyzed in the first gyrokinetic simulation spanning all scales from the tail of the MHD range to the elect…
PHL 1445: An eclipsing cataclysmic variable with a substellar donor near the period minimum
M. J. McAllister, S. P. Littlefair, I. Baraffe +14
We present high-speed, three-colour photometry of the eclipsing dwarf nova PHL 1445, which, with an orbital period of 76.3 min, lies just below the period minimum of ~82 min for ca…
TOPoS: II. On the bimodality of carbon abundance in CEMP stars. Implications on the early chemical evolution of galaxies
P. Bonifacio, E. Caffau, M. Spite +18
In the course of the TOPoS (Turn Off Primordial Stars) survey, aimed at discovering the lowest metallicity stars, we have found several carbon-enhanced metal-poor (CEMP) stars. We…
The normal chemistry of multiple stellar populations in the dense globular cluster NGC 6093 (M 80)
E. Carretta, A. Bragaglia, R. G. Gratton +6
We present the abundance analysis of 82 red giant branch stars in the dense, metal-poor globular cluster NGC 6093 (M 80), the largest sample of stars analyzed in this way for this…
The accretion histories of brightest cluster galaxies from their stellar population gradients
Paola Oliva-Altamirano, Sarah Brough, Jimmy +6
We analyse the spatially-resolved stellar populations of 9 local () Brightest Cluster Galaxies (BCGs) observed with VIMOS in IFU mode. Our sample is composed of 7 slow-rotat…
Evidence of tidal distortions and mass loss from the old open cluster NGC 6791
E. Dalessandro, P. Miocchi, G. Carraro +2
We present the first evidence of clear signatures of tidal distortions in the density distribution of the fascinating open cluster NGC 6791. We used deep and wide-field data obtain…
Surface state reconstruction in ion-damaged SmB_6
N. Wakeham, Y. Q. Wang, Z. Fisk +2
We have used ion-irradiation to damage the (001) surfaces of SmB_6 single crystals to varying depths, and have measured the resistivity as a function of temperature for each depth…
