Stellar kinematics in double-barred galaxies: the sigma-hollows
A. de Lorenzo-Cáceres, J. Falcón-Barroso, A. Vazdekis +1
We present SAURON integral-field stellar velocity and velocity dispersion maps for four double-barred early-type galaxies: NGC2859, NGC3941, NGC4725 and NGC5850. The presence of th…
A New Hubble Space Telescope Distance to NGC 1569: Starburst Properties and IC 342 Group Membership
Aaron J. Grocholski, Alessandra Aloisi, Roeland P. van der Marel +8
We present deep HST ACS/WFC photometry of the dwarf irregular galaxy NGC 1569, one of the closest and strongest nearby starburst galaxies. These data allow us, for the first time,…
The Magellanic Cloud Calibration of the Galactic Planetary Nebula Distance Scale
Letizia Stanghellini, Richard A. Shaw, Eva Villaver
Galactic planetary nebula (PN) distances are derived, except in a small number of cases, through the calibration of statistical properties of PNe. Such calibrations are limited by…
Testing magnetically confined wind shock models for Beta Cep using XMM-Newton and Chandra phase-resolved X-ray observations
F. Favata, C. Neiner, P. Testa +2
(abridged) We have performed a set of phase-resolved X-ray observations of the magnetic B star Beta Cep, for which theoretical models predict the presence of a confined wind emitti…
Holmberg Ix: The Nearest Young Galaxy
E. Sabbi, J. S. Gallagher, L. J. Smith +2
Deep images taken with the Wide Field Channel of the Advanced Camera for Surveys on board the Hubble Space Telescope provide the basis for study the resolved stellar population of…
Cosmic dynamics in the era of Extremely Large Telescopes
J. Liske, A. Grazian, E. Vanzella +24
The redshifts of all cosmologically distant sources are expected to experience a small, systematic drift as a function of time due to the evolution of the Universe's expansion rate…
