Walking with SOXS towards the transient sky
P. Schipani, S. Campana, R. Claudi +59
SOXS (Son Of X-Shooter) is the new ESO instrument that is going to be installed on the 3.58-m New Technology Telescope at the La Silla Observatory. SOXS is a single object spectrog…
Shock Excitation in Narrow Line Regions Powered by AGN Outflows
Misaki Mizumoto, Hiroaki Sameshima, Naoto Kobayashi +10
Outflows in the Active Galactic Nucleus (AGN) are considered to play a key role in the host galaxy evolution through transfer of a large amount of energy. A Narrow Line Region (NLR…
Sky Quality Meter and satellite correlation for the night cloud cover analysis at astronomical sites
S. Cavazzani, S. Ortolani, A. Bertolo +5
The analysis of the night cloud cover is very important for astronomical observation in real time, considering a typical observation time of about 15 minutes, and to have a statist…
The vertical Na-O relation in the bulge globular cluster NGC 6553
C. Muñoz, S. Villanova, D. Geisler +7
In this article, we present a detailed chemical analysis of seven red giant members of NGC 6553 using high-resolution spectroscopy from VLT FLAMES. We obtained the stellar paramete…
Another relic bulge globular cluster: ESO 456-SC38 (Djorgovski~2)
S. Ortolani, E. V. Held, D. Nardiello +7
The object ESO456-SC38 (Djorgovski 2) is one of the globular clusters that is closest to the Galactic center. It is on the blue horizontal branch and has a moderate metallicity of…
Variable broad lines and outflow in the weak blazar PBC J2333.9-2343
L. Hernández-García, G. Vietri, F. Panessa +12
PBC J2333.9-2343 is a peculiar active nucleus with two giant radio lobes and a weak blazar-like nucleus at their center. In the present work we show new optical, UV, and X-ray data…
The chemical composition of the stellar cluster Gaia1: no surprise behind Sirius
A. Mucciarelli, L. Monaco, P. Bonifacio +1
We observed 6 He-clump stars of the intermediate-age stellar cluster Gaia1 with the MIKE/MAGELLAN spectrograph. A possible extra-galactic origin of this cluster, recently discovere…
The peculiar Na-O anticorrelation of the bulge globular cluster NGC 6440
C. Muñoz, S. Villanova, D. Geisler +4
Context. Galactic Globular Clusters (GCs) are essential tools to understand the earliest epoch of the Milky Way, since they are among the oldest objects in the Universe and can be…
An extensive radial velocity survey toward NGC 6253
M. Montalto, C. H. F. Melo, N. C. Santos +6
The old and metal rich open cluster NGC 6253 was observed with the FLAMES multi-object spectrograph during an extensive radial velocity campaign monitoring 317 stars with a median…
NGC 5824: a luminous outer halo globular cluster with an intrinsic abundance spread
G. S. Da Costa, E. V. Held, I. Saviane
We present a detailed study of the strengths of the calcium triplet absorption lines in the spectra of a large sample of red giant members of the luminous outer Galactic halo globu…
High Resolution HDS/SUBARU chemical abundances of the young stellar cluster Palomar 1
L. Monaco, I. Saviane, M. Correnti +2
Context. Palomar\,1 is a peculiar globular cluster (GC). It is the youngest Galactic GC and it has been tentatively associated to several of the substructures recently discovered i…
A multiwavelength view of the protostellar binary IRAS04325+2402: a case for turbulent fragmentation
A. Scholz, K. Wood, D. Wilner +6
IRAS04325+2402 (herafter IRAS04325) is a complex protostellar system hosting two young stellar objects (AB and C in the following) at a separation of 1250AU. Here we present new de…
