ATCA detections of massive molecular gas reservoirs in dusty, high-z radio galaxies
Ivison, R. J.; Cooray, A.; Ibar, E. +9 more
Observations using the 7-mm receiver system on the Australia Telescope Compact Array have revealed large reservoirs of molecular gas in two high-redshift radio galaxies: HATLAS J090426.9+015448 (z = 2.37) and HATLAS J140930.4+003803 (z = 2.04). Optically, the targets are very faint, and spectroscopy classifies them as narrow-line radio galaxies. I…
Characterization of the warm-hot intergalactic medium near the Coma cluster through high-resolution spectroscopy of X Comae
Bonamente, M.; Morandi, A.; Tempel, E. +2 more
We have analysed all available archival XMM-Newton observations of X Comae, a bright X-ray quasar behind the Coma cluster, to study the properties of the warm-hot intergalactic medium (WHIM) in the vicinity of the nearest massive galaxy cluster. The reflection grating spectrometer observations confirm the possible presence of a Ne ix K α absorptio…
Corrigendum to "Observation of Neon at mid and high latitudes in the sunlit Lunar Exosphere: Results from CHACE aboard MIP/Chandrayaan-1", Vol. 272 (2016), pp 206-211, doi 10.1016/j.icarus.2016.02.030
Bhardwaj, Anil; Sridharan, R.; Thampi, Smitha V. +2 more
Our paper titled "Observation of Neon at mid and high latitudes in the sunlit Lunar Exosphere: Results from CHACE aboard MIP/Chandrayaan-1" (Icarus 272 (2016) 206-211) presents the results of the observations on the distribution of neutral Neon in the mid and high lunar latitudes by the CHACE instrument aboard Moon Impact Probe (MIP) in Chandrayaa…
A parallel model for SQL astronomical databases based on solid state storage. Application to the Gaia Archive PostgreSQL database
González-Núñez, J.; Gutiérrez-Sánchez, R.; Segovia, J. C. +3 more
Query planning and optimisation algorithms in most popular relational databases were developed at the times hard disk drives were the only storage technology available. The advent of higher parallel random access capacity devices, such as solid state disks, opens up the way for intra-machine parallel computing over large datasets.

de Wijn, A. G.; Socas-Navarro, H.; Vitas, N.
We report on the detection of linear polarization of the forbidden [O I] 630.03 nm spectral line. The observations were carried out in the broader context of the determination of the solar oxygen abundance, an important problem in astrophysics that still remains unresolved. We obtained spectro-polarimetric data of the forbidden [O I] line at 630.0…
Point and Compact Hα Sources in the Interior of M33
Joner, Michael D.; Roming, Peter W. A.; Hintz, Eric G. +2 more
A variety of interesting objects such as Wolf-Rayet stars, tight OB associations, planetary nebulae, X-ray binaries, etc., can be discovered as point or compact sources in Hα surveys. How these objects distribute through a galaxy sheds light on the galaxy star formation rate and history, mass distribution, and dynamics. The nearby galaxy M33 is an…
A New Orbit for the Eclipsing Binary V577 Oph
Jeffery, Elizabeth J.; Barnes, Thomas G., III; Skillen, Ian +1 more
Pulsating stars in eclipsing binary systems are unique objects for providing constraints on stellar models. To fully leverage the information available from the binary system, full orbital radial velocity curves must be obtained. We report 23 radial velocities for components of the eclipsing binary V577 Oph, whose primary star is a δ Sct variable.…

Halo Pressure Profile through the Skew Cross-power Spectrum of the Sunyaev-Zel’dovich Effect and CMB Lensing in Planck
Cooray, Asantha; Feng, Chang; Keating, Brian +1 more
We measure the cosmic microwave background (CMB) skewness power spectrum in Planck, using frequency maps of the HFI instrument and the Sunyaev-Zel’dovich (SZ) component map. The two-to-one skewness power spectrum measures the cross-correlation between CMB lensing and the thermal SZ effect. We also directly measure the same cross-correlation using …
The XMM deep survey in the Chandra Deep Field South
Vignali, C.; Gilli, R.; Ranalli, P. +3 more
The Chandra Deep Field South (CDF-S) was observed by XMM-Newton for about 3 Ms in many periods over the past decade (2001-2002 and 2008-2009). The main goal of the survey was to obtain good quality X-ray spectroscopy of the active galactic nuclei responsible for the bulk of the X-ray background. We present the scientific highlights of the XMM-Newt…
