Large-scale clustering measurements with photometric redshifts: comparing the dark matter haloes of X-ray AGN, star-forming and passive galaxies at z ≈ 1
Berta, S.; Magnelli, B.; Lutz, D. +11 more
We combine multi-wavelength data in the AEGIS-XD and C-COSMOS surveys to measure the typical dark matter halo mass of X-ray selected active galactic nuclei (AGN) [LX(2-10 keV) > 1042 erg s- 1] in comparison with far-infrared selected star-forming galaxies detected in the Herschel/PEP survey (PACS Evolutionary Pr…
Imaging Observations of X-Ray Quasi-periodic Oscillations at 3 - 6 keV in the 26 December 2002 Solar Flare
Ning, Zongjun
Quasi-periodic oscillations in soft X-rays (SXR) are not well known due to the instrument limitations, especially the absence of imaging observations of SXR oscillations. We explore the quasi-periodic oscillations of SXR at 3 - 6 keV in a solar flare observed by the Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI) on 26 December 2002.…
Spatial and temporal dependence of the convective electric field in Saturn’s inner magnetosphere
Krupp, N.; Dougherty, M. K.; Roussos, E. +5 more
The recently established presence of a convective electric field in Saturn’s inner and middle magnetosphere, with an average pointing approximately towards midnight and an intensity less than 1 mV/m, is one of the most puzzling findings by the Cassini spacecraft. In order to better characterize the properties of this electric field, we augmented t…
Giada: its Status after the Rosetta Cruise Phase and On-Ground Activity in Support of the Encounter with Comet 67P/CHURYUMOV-GERASIMENKO
Lamy, P.; Fulle, M.; Rodrigo, R. +33 more
GIADA (Grain Impact Analyser and Dust Accumulator) on-board the Rosetta mission to comet 67P/Churyumov-Gerasimenko was designed to study the physical and dynamical properties of dust particles ejected by the comet during the encounter. In this paper we report the results of the analysis of data collected by GIADA during the past seven years of the…
The population of early-type galaxies: how it evolves with time and how it differs from passive and late-type galaxies
Longhetti, M.; Gargiulo, A.; Saracco, P. +3 more
Aims: There are two aims to our analysis. On the one hand we are interested in addressing whether a sample of morphologically selected early-type galaxies (ETGs) differs from a sample of passive galaxies in terms of galaxy statistics. On the other hand we study how the relative abundance of galaxies, the number density, and, the stellar mass …
Around the Ring We Go: The Cold, Dense Ring of Molecular Gas in NGC 1614
Wilson, Christine D.; Iono, Daisuke; Matsushita, Satoki +2 more
We present high-resolution archival Atacama Large Millimeter/submillimeter Array (ALMA) 12CO J = 3-2 and J = 6-5 and HCO+ J = 4-3 observations and new CARMA 12CO and 13CO J = 1-0 observations of the luminous infrared galaxy NGC 1614. The high-resolution maps show the previously identified ring-like struc…
Four new X-ray-selected supernova remnants in the Large Magellanic Cloud
Pietsch, W.; Haberl, F.; Gruendl, R. A. +8 more
Aims: We present a detailed multi-wavelength study of four new supernova remnants (SNRs) in the Large Magellanic Cloud (LMC). The objects were identified as SNR candidates in X-ray observations performed during the survey of the LMC with XMM-Newton.
Methods: Data obained with XMM-Newton are used to investigate the morphological and spect…
Herschel/PACS observations of the 69 µm band of crystalline olivine around evolved stars
Waters, L. B. F. M.; Blommaert, J. A. D. L.; García-Lario, P. +15 more
Context. We present 48 Herschel/PACS spectra of evolved stars in the wavelength range of 67-72 µm. This wavelength range covers the 69 µm band of crystalline olivine (Mg2-2xFe(2x)SiO4). The width and wavelength position of this band are sensitive to the temperature and composition of the crystalline oli…
Constraining the Lyα Escape Fraction with Far-infrared Observations of Lyα Emitters
Ivison, R. J.; Wang, L.; Bock, J. +22 more
We study the far-infrared properties of 498 Lyα emitters (LAEs) at z = 2.8, 3.1, and 4.5 in the Extended Chandra Deep Field-South, using 250, 350, and 500 µm data from the Herschel Multi-tiered Extragalactic Survey and 870 µm data from the LABOCA ECDFS Submillimeter Survey. None of the 126, 280, or 92 LAEs at z = 2.8, 3.1, and 4.5, res…
The Variable Sky of Deep Synoptic Surveys
Matheson, Thomas; Howell, Steve B.; Mighell, Kenneth J. +2 more
The discovery of variable and transient sources is an essential product of synoptic surveys. The alert stream will require filtering for personalized criteria—a process managed by a functionality commonly described as a Broker. In order to understand quantitatively the magnitude of the alert generation and Broker tasks, we have undertaken an analy…
