Chemical abundances and radial velocities in the extremely metal-poor galaxy DDO 68
F. Annibali, V. La Torre, M. Tosi +9
We present chemical abundances and radial velocities of six HII regions in the extremely metal-poor star-forming dwarf galaxy DDO 68. They are derived from deep spectra in the wave…
Homogeneous metallicities and radial velocities for Galactic globular clusters. II. New CaT metallicities for 28 distant and reddened globular clusters
S. Vásquez, I. Saviane, E. V. Held +6
Although the globular clusters in the Milky Way have been studied for a long time, a significant fraction of them lack homogeneous metallicity and radial velocity measurements. In…
VERA monitoring of the radio jet 3C 84 during 2007--2013: detection of non-linear motion
Koichiro Hiura, Hiroshi Nagai, Motoki Kino +13
We present a kinematic study of the subparsec-scale radio jet of the radio galaxy 3C 84/NGC 1275 with the VLBI Exploration of Radio Astrometry (VERA) array at 22 GHz for 80 epochs…
AGB candidates in the field of gamma Cas
Roberto Nesci, Taavi Tuvikene, Corinne Rossi +5
We report the spectroscopic and photometric monitoring of a sample of 530 candidate AGB stars in a 5 degrees field, selected from the IPHAS catalog: historic light curves were deri…
LBT/MODS spectroscopy of globular clusters in the irregular galaxy NGC 4449
F. Annibali, E. Morandi, L. L. Watkins +11
We present intermediate-resolution (R1000) spectra in the 3500-10,000 A range of 14 globular clusters in the magellanic irregular galaxy NGC 4449 acquired with the Mult…
