MOIRCS Deep Survey. IX. Deep Near-Infrared Imaging Data and Source Catalog
Ouchi, Masami; Tanaka, Ichi; Yamada, Toru +13 more
We present deep J-, H-, and Ks-band imaging data of the MOIRCS Deep Survey (MODS), which was carried out with the Multi-Object Infrared Camera and Spectrograph (MOIRCS) mounted on the Subaru Telescope in the GOODS-North region. The data reach 5σ total limiting magnitudes for point sources of J = 23.9, H = 22.8, and Ks = 22.8 …
Spitzer Infrared Spectrometer 16 µm Observations of the Goods Fields
Papovich, Casey; Dickinson, Mark; Teplitz, Harry I. +13 more
We present Spitzer 16 µm imaging of the Great Observatories Origins Deep Survey (GOODS) fields. We survey 150 arcmin2 in each of the two GOODS fields (North and South), to an average 3σ depth of 40 and 65 µJy, respectively. We detect ~1300 sources in both fields combined. We validate the photometry using the 3-24 µm sp…
Luminosity functions of local infrared galaxies with AKARI: implications for the cosmic star formation history and AGN evolution
Goto, Tomotsugu; Inami, Hanae; Nakagawa, Takao +15 more
Infrared (IR) luminosity is fundamental to understanding the cosmic star formation history and active galactic nuclei (AGN) evolution, since their most intense stages are often obscured by dust. However, local IR luminosity function estimates today are still based on the IRAS survey in the 1980s, with wavelength coverage only up to 100 µm. T…
Multi-epoch X-ray observations of the Seyfert 1.2 galaxy Mrk 79: bulk motion of the illuminating X-ray source
Guainazzi, M.; Fabian, A. C.; Miller, J. M. +4 more
Multi-epoch X-ray spectroscopy (0.3-25 keV) of the Seyfert 1.2 galaxy Mrk 79 (UGC 3973) spanning nearly 8 yr and a factor of 3 in broad-band flux are analysed. The data are obtained at seven epochs with either XMM-Newton or Suzaku. Comparison with contemporaneous RXTE monitoring indicates that all flux states of Mrk 79 are represented by the data.…
A CANDELS WFC3 Grism Study of Emission-line Galaxies at z ~ 2: A Mix of Nuclear Activity and Low-metallicity Star Formation
Finkelstein, Steven L.; Bell, Eric F.; Dickinson, Mark +26 more
We present Hubble Space Telescope Wide Field Camera 3 (WFC3) slitless grism spectroscopy of 28 emission-line galaxies at z ~ 2, in the GOODS-S region of the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey. The high sensitivity of these grism observations, with >1σ detections of emission lines to f > 2.5 × 10-18 erg …
Magnetoseismological Determination of Magnetic Field and Plasma Density Height Variation in a Solar Spicule
Goossens, M.; Verth, G.; He, J. -S.
The variation of magnetic field strength and plasma density along a solar spicule is determined by the use of magnetoseismology. From Solar Optical Telescope observations of a kink wave propagating along a spicule, by estimating the spatial change in phase speed and velocity amplitude, a novel approach is demonstrated to determine the chromospheri…
The Sloan Lens ACS Survey. XI. Beyond Hubble Resolution: Size, Luminosity, and Stellar Mass of Compact Lensed Galaxies at Intermediate Redshift
Treu, Tommaso; Marshall, Philip J.; Auger, Matthew W. +5 more
We exploit the strong lensing effect to explore the properties of intrinsically faint and compact galaxies at intermediate redshift (z s ~= 0.4-0.8) at the highest possible resolution at optical wavelengths. Our sample consists of 46 strongly lensed emission line galaxies (ELGs) discovered by the Sloan Lens ACS Survey (SLACS). The galax…
Evolution of X-ray and Far-ultraviolet Disk-dispersing Radiation Fields
Briceño, Cesar; Hartmann, Lee; Calvet, Nuria +5 more
We present new X-ray and far-ultraviolet (FUV) observations of T Tauri stars covering the age range 1-10 Myr. Our goals are to observationally constrain the intensity of radiation fields responsible for evaporating gas from the circumstellar disk and to assess the feasibility of current photoevaporation models, focusing on X-ray and UV radiation. …
Condensation in Titan's atmosphere at the Huygens landing site
Yelle, R. V.; Lavvas, P.; Griffith, C. A.
We present a self-consistent description of Titan's aerosols-clouds-gases system and compare our results with the optical properties retrieved from measurements made by the Descent Imager/Spectral Radiometer (DISR) experiment on the Huygens probe (Tomasko, M.G. et al. [2008]. Planet. Space Sci. 56, 669-707). Our calculations include the condensati…
Magnetopause reconnection across wide local time
Berchem, J.; Eastwood, J. P.; Lavraud, B. +19 more
During April to July 2007 a combination of 10 spacecraft provided simultaneous monitoring of the dayside magnetopause across a wide range of local times. The array of four Cluster spacecraft, separated at large distances (10 000 km), were traversing the dawn-side magnetopause at high and low latitudes; the five THEMIS spacecraft were often in a 4 …
