INTEGRAL/IBIS nine-year Galactic hard X-ray survey
Sunyaev, R.; Krivonos, R.; Tsygankov, S. +3 more
Context. The INTEGRAL observatory operating in a hard X-ray/gamma domain has gathered a large observational data set over nine years starting in 2003. Most of the observing time was dedicated to the Galactic source population study, making possible the deepest Galactic survey in hard X-rays ever compiled.
Aims: We aim to perform a Galactic su…
The first INTEGRAL-OMC catalogue of optically variable sources
Mas-Hesse, J. M.; Domingo, A.; Alfonso-Garzón, J. +1 more
Context. The Optical Monitoring Camera (OMC) onboard INTEGRAL provides photometry in the Johnson V-band. With an aperture of 50 mm and a field of view of 5° × 5°, OMC is able to detect optical sources brighter than V ~ 18, from a previously selected list of potential targets of interest. After more than nine years of observations, the OMC database…
Herschel observations of B1-bS and B1-bN: two first hydrostatic core candidates in the Perseus star-forming cloud
Hill, T.; White, G. J.; Könyves, V. +24 more
We report far-infrared Herschel observations obtained between 70 µm and 500 µm of two star-forming dusty condensations,
Submillimetre photometry of 323 nearby galaxies from the Herschel Reference Survey
Clements, D. L.; Ciesla, L.; Buat, V. +23 more
The Herschel Reference Survey (HRS) is a guaranteed time Herschel key project aimed at studying the physical properties of the interstellar medium in galaxies of the nearby universe. This volume limited, K-band selected sample is composed of galaxies spanning the whole range of morphological types (from ellipticals to late-type spirals) and enviro…
The dust properties of bubble H II regions as seen by Herschel
Abergel, A.; Bernard, J. -P.; Hill, T. +10 more
Context. Because of their relatively simple morphology, "bubble" H II regions have been instrumental to our understanding of star formation triggered by H II regions. With the far-infrared (FIR) spectral coverage of the Herschel satellite, we can access the wavelengths where these regions emit the majority of their energy through their dust emissi…
The size-luminosity relation at z = 7 in CANDELS and its implication on reionization
Ferguson, H. C.; Giavalisco, M.; McLure, R. J. +15 more
Context. The exploration of the relation between galaxy sizes and other physical parameters (luminosity, mass, star formation rate) has provided important clues for understanding galaxy formation, but such exploration has until recently been limited to intermediate redshift objects.
Aims: We use the currently available CANDELS Deep+Wide surve…
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…
The blue UV slopes of z ~ 4 Lyman break galaxies: implications for the corrected star formation rate density
Maiolino, R.; Castellano, M.; Pentericci, L. +13 more
Context. Study of the dust extinction in high-redshift galaxies is fundamental to obtaining an estimate of the corrected star formation rate density (SFRD) and to put constraints on galaxy evolution models.
Aims: We plan to analyse dust extinction in Lyman break galaxies (LBGs) by introducing a new and more reliable approach to their selectio…
Reconstruction of total solar irradiance 1974-2009
Jaffe, A. H.; Krivova, N. A.; Solanki, S. +4 more
Context. The study of variations in total solar irradiance (TSI) is important for understanding how the Sun affects the Earth's climate.
Aims: Full-disk continuum images and magnetograms are now available for three full solar cycles. We investigate how modelled TSI compares with direct observations by building a consistent modelled TSI datase…
Stellar population models in the UV. I. Characterisation of the New Generation Stellar Library
Koleva, M.; Vazdekis, A.
Context. The spectral predictions of stellar population models are not as accurate in the ultra-violet (UV) as in the optical wavelength domain. One of the reasons is the lack of high-quality stellar libraries. The New Generation Stellar Library (NGSL), recently released, represents a significant step towards the improvement of this situation.
