Young Massive Clusters in Non-Interacting Galaxies
S. S. Larsen, J. P. Brodie, D. A. Hunter +1
Young star clusters with masses well in excess of 100.000 Msun have been observed not only in merger galaxies and large-scale starbursts, but also in fairly normal, undisturbed spi…
'Sculptor'-ing the Galaxy? The Chemical Compositions of Red Giants in the Sculptor Dwarf Spheroidal Galaxy
Doug Geisler, Verne V. Smith, George Wallerstein +2
We have used high-resolution, high signal-to-noise spectra obtained with the VLT and UVES to determine abundances of 17 elements in 4 red giants in the Sculptor dwarf spheroidal ga…
Classical Cepheid Pulsation Models. X. The Period-Age Relation
G. Bono, M. Marconi, S. Cassisi +3
We present new Period-Age (PA) and Period-Age-Color (PAC) relations for fundamental and first overtone classical Cepheids. Current predictions rely on homogeneous sets of evolution…
Mass-to-light ratio gradients in early-type galaxy haloes
N. R. Napolitano, M. Capaccioli, A. J. Romanowsky +6
Since the near future should see a rapidly expanding set of probes of the halo masses of individual early-type galaxies, we introduce a convenient parameter for characterising the…
TV Corvi Revisited: Precursor and Superhump Period Derivative Linked to the Disk Instability Model
M. Uemura, R. E. Mennickent, R. Ishioka +9
We report optical photometric observations of four superoutbursts of the short-period dwarf nova TV Crv. This object experiences two types of superoutbursts; one with a precursor a…
Generation of maximally entangled states of qudits using twin photons
Leonardo Neves, G. Lima, J. G. Aguirre Gómez +3
We report an experiment to generate maximally entangled states of D-dimensional quantum systems, qudits, by using transverse spatial correlations of two parametric down-converted p…
