The XMM-Newton serendipitous ultraviolet source survey catalogue
Talavera, A.; Page, M. J.; Cropper, M. S. +11 more
The XMM-Newton Serendipitous Ultraviolet Source Survey (XMM-SUSS) is a catalogue of ultraviolet (UV) sources detected serendipitously by the Optical Monitor (XMM-OM) on board the XMM-Newton observatory. The catalogue contains UV-detected sources collected from 2417 XMM-OM observations in one to six broad-band UV and optical filters, made between 2…
Magnetospheric configuration and dynamics of Saturn's magnetosphere: A global MHD simulation
Hansen, Kenneth C.; Gombosi, Tamas I.; Kivelson, Margaret G. +4 more
We investigate the solar wind interaction with Saturn's magnetosphere by using a global magnetohydrodynamic simulation driven by an idealized time-varying solar wind input that includes features of Corotating Interaction Regions typically seen at Saturn. Our model results indicate that the compressibility of Saturn's magnetosphere is intermediate …
[C II] 158 µm Luminosities and Star Formation Rate in Dusty Starbursts and Active Galactic Nuclei
Lebouteiller, V.; Engels, D.; Stacey, G. +8 more
Results are presented for [C II] 158 µm line fluxes observed with the Herschel PACS instrument in 112 sources with both starburst and active galactic nucleus (AGN) classifications, of which 102 sources have confident detections. Results are compared with mid-infrared spectra from the Spitzer Infrared Spectrometer and with L ir fro…
The UVJ Selection of Quiescent and Star-forming Galaxies: Separating Early- and Late-type Galaxies and Isolating Edge-on Spirals
Franx, Marijn; Kelson, Daniel D.; Illingworth, Garth D. +3 more
We utilize for the first time Hubble Space Telescope Advanced Camera for Surveys imaging to examine the structural properties of galaxies in the rest-frame U - V versus V - J diagram (i.e., the UVJ diagram) using a sample at 0.6 < z < 0.9 that reaches a low stellar mass limit (log M/M ⊙ >10.25). The use of the UVJ diagram as a …
Remote and in situ observations of an unusual Earth-directed coronal mass ejection from multiple viewpoints
Anderson, B. J.; Szabo, A.; Nieves-Chinchilla, T. +5 more
During June 16-21, 2010, an Earth-directed coronal mass ejection (CME) event was observed by instruments onboard STEREO, SOHO, MESSENGER and Wind. This event was the first direct detection of a rotating CME in the middle and outer corona. Here, we carry out a comprehensive analysis of the evolution of the CME in the interplanetary medium comparing…
On Spectral Breaks in the Power Spectra of Magnetic Fluctuations in Fast Solar Wind between 0.3 and 0.9 AU
Maksimovic, M.; Alexandrova, O.; Marsch, E. +1 more
We analyze the radial variation of the power spectra of the magnetic field from 0.3 to about 0.9 AU, using Helios 2 spacecraft measurements in the fast solar wind. The time resolution of the magnetic field data allows us to study the power spectra up to 2 Hz. Generally, the corresponding spectral break frequency fb and the Doppler-shift…
Magnetosheath pressure pulses: Generation downstream of the bow shock from solar wind discontinuities
Eastwood, J. P.; Horbury, T. S.; Archer, M. O.
We present multipoint Time History of Events and Macroscale Interactions during Substorms (THEMIS) observations of transient dynamic pressure pulses in the magnetosheath 3-10 times the background in amplitude, due to enhancements in both the ion density and velocity. Their spatial dimensions are of the order of ∼1 RE parallel to the flo…
The importance of plasma β conditions for magnetic reconnection at Saturn's magnetopause
Coates, A. J.; Russell, C. T.; Dougherty, M. K. +7 more
Magnetic reconnection is an important process that occurs at the magnetopause boundary of Earth's magnetosphere because it leads to transport of solar wind energy into the system, driving magnetospheric dynamics. However, the nature of magnetopause reconnection in the case of Saturn's magnetosphere is unclear. Based on a combination of Cassini spa…
Re-evaluating WASP-12b: Strong Emission at 2.315 µm, Deeper Occultations, and an Isothermal Atmosphere
Barman, Travis; Crossfield, Ian J. M.; Kodama, Tadayuki +2 more
We revisit the atmospheric properties of the extremely hot Jupiter WASP-12b in light of several new developments. First, we present new narrowband (2.315 µm) secondary eclipse photometry, which exhibits a planet/star flux ratio of 0.45% ± 0.06%, corresponding to a brightness temperature of 3640 ± 230 K; second, recent Spitzer/Infrared Array …
GOODS-Herschel: ultra-deep XMM-Newton observations reveal AGN/star-formation connection
Magnelli, B.; Altieri, B.; Aussel, H. +30 more
Models of galaxy evolution assume some connection between the AGN and star formation activity in galaxies. We use the multi-wavelength information of the CDFS to assess this issue. We select the AGNs from the 3 Ms XMM-Newton survey and measure the star-formation rates of their hosts using data that probe rest-frame wavelengths longward of 20 &micr…
