A Multi-Color Optical Survey of the Orion Nebula Cluster. Part I: the Catalog

Nicola Da Rio, Massimo Robberto, David R. Soderblom +4

We present U, B, V, I broad-band, 6200A TiO medium-band and Halpha photometry of the Orion Nebula Cluster obtained with the WFI imager at the ESO/MPI 2.2 telescope. The nearly-simu…

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…

Trigonometric Parallaxes of Massive Star Forming Regions: VI. Galactic Structure, Fundamental Parameters and Non-Circular Motions

M. J. Reid, K. M. Menten, X. W. Zheng +11

We are using the VLBA and the Japanese VERA project to measure trigonometric parallaxes and proper motions of masers found in high-mass star-forming regions across the Milky Way. E…
