Distribution of magnetic fields in the quiet Sun
Faurobert, M.; Ricort, G.
Context. The distribution of magnetic fields in the atmosphere of the quiet Sun has been extensively studied with various methods, but it is still a matter of debate. Previous analyses mostly rely on the inversion of spectro-polarimetric data and different methods lead to somewhat different results.
Aims: Here we do not intend to determine th…
Observability of YSOs with the WISE and AKARI infrared space observatories
Tamura, M.; Marton, G.; Ueno, M. +4 more
Large area surveys allow us to identify young stellar objects and classify them based on their colours. The near-, mid- and far-infrared filters' sensitivities are different, therefore different proportions of young stars are observable. Evolutionary times for the different classes can be concluded from the popularity of the classes. Our aim was t…
Cassini High Rate Detector V12.0
Economou, T.; DiDonna, P.
The High Rate Detector (HRD) from the University of Chicago is an independent part of the CDA instrument on the Cassini Orbiter that measures the dust flux and particle mass distribution of dust particles hitting the HRD detectors. This data set includes all data from the HRD through December 31, 2012. Please refer to Srama et al. (2004) for a det…
Sunyaev-Zel'dovich effect or not ? detecting the main foreground effect of most galaxy clusters.
Zhang, B.; Wu, Y.; Xiao, W. +2 more
Galaxy clusters are the most massive objects in the Universe and comprise a high-temperature intracluster medium of about 107 K, believed to offer a main foreground effect for cosmic microwave background (CMB) data in the form of the thermal Sunyaev-Zel'dovich (SZ) effect. This assumption has been confirmed by SZ signal detection in hun…
Gaskell Tethys Shape Model V1.0
Gaskell, R. W.
The shape model of Tethys derived by Robert Gaskell from Cassini Imaging Science Subsystem narrow and wide angle camera (ISSNA and ISSWA) images. The model is provided in the implicitly connected quadrilateral (ICQ) format. This version of the model was prepared on July 25, 2012. Vertex-facet versions of the models are also provided.
Star Formation in the Milky Way and Nearby Galaxies
Kennicutt, Robert C.; Evans, Neal J.
We review progress over the past decade in observations of large-scale star formation, with a focus on the interface between extragalactic and Galactic studies. Methods of measuring gas contents and star-formation rates are discussed, and updated prescriptions for calculating star-formation rates are provided. We review relations between star form…
The Hubble Space Telescope Cluster Supernova Survey. V. Improving the Dark-energy Constraints above z > 1 and Building an Early-type-hosted Supernova Sample
Gladders, M. D.; Panagia, N.; Stern, D. +63 more
We present Advanced Camera for Surveys, NICMOS, and Keck adaptive-optics-assisted photometry of 20 Type Ia supernovae (SNe Ia) from the Hubble Space Telescope (HST) Cluster Supernova Survey. The SNe Ia were discovered over the redshift interval 0.623 < z < 1.415. Of these SNe Ia, 14 pass our strict selection cuts and are used in combination …
The Cluster Lensing and Supernova Survey with Hubble: An Overview
Donahue, Megan; Broadhurst, Tom; Moustakas, John +42 more
The Cluster Lensing And Supernova survey with Hubble (CLASH) is a 524-orbit Multi-Cycle Treasury Program to use the gravitational lensing properties of 25 galaxy clusters to accurately constrain their mass distributions. The survey, described in detail in this paper, will definitively establish the degree of concentration of dark matter in the clu…
Mid-infrared Selection of Active Galactic Nuclei with the Wide-Field Infrared Survey Explorer. I. Characterizing WISE-selected Active Galactic Nuclei in COSMOS
Tsai, Chao-Wei; Dey, Arjun; Griffith, Roger L. +15 more
The Wide-field Infrared Survey Explorer (WISE) is an extremely capable and efficient black hole finder. We present a simple mid-infrared color criterion, W1 - W2 >= 0.8 (i.e., [3.4]-[4.6] >=0.8, Vega), which identifies 61.9 ± 5.4 active galactic nucleus (AGN) candidates per deg2 to a depth of W2 ~ 15.0. This implies a much larger …
UltraVISTA: a new ultra-deep near-infrared survey in COSMOS
Sutherland, W.; Milvang-Jensen, B.; Fynbo, J. P. U. +18 more
In this paper we describe the first data release of the UltraVISTA near-infrared imaging survey of the COSMOS field. We summarise the key goals and design of the survey and provide a detailed description of our data reduction techniques. We provide stacked, sky-subtracted images in YJHKs and narrow-band filters constructed from data col…
