XMM-Newton surveys of the Canada-France Redshift Survey fields - I. The submillimetre/X-ray relation
Eales, Stephen A.; Thuan, Trinh X.; Gear, Walter K. +7 more
First results from XMM-Newton observations of the Canada-France Redshift Survey (CFRS) 3-h, 10-h and 14-h fields are presented. Limited regions of two of the XMM surveys (3 and 14 h) are compared with the Canada-UK Deep Submillimetre Surveys (CUDSS) undertaken with SCUBA. None of the 27 SCUBA sources in the 3-h field is detected by XMM, while one …
An empirical test of the theoretical population corrections to the red clump absolute magnitude
Salaris, Maurizio; Percival, Susan M.
The mean absolute magnitude of the local red clump (RC), MRCλ, is a very well-determined quantity owing to the availability of accurate Hipparcos parallaxes for several hundred RC stars, potentially allowing it to be used as an accurate extragalactic distance indicator. Theoretical models predict that the RC mean magnitude is…
Inverse Compton X-rays from the radio galaxy 3C 219
Bondi, M.; Brunetti, G.; Comastri, A. +3 more
We report the results from a Chandra observation of the powerful nearby (z= 0.1744) radio galaxy 3C 219. We find evidence for non-thermal X-ray emission from the radio lobes which fits fairly well with a combination of inverse Compton scattering of Cosmic Microwave Background radiation and of nuclear photons with the relativistic electrons in the …
The redshift of the Einstein ring in MG 1549+305
Treu, T.; Koopmans, L. V. E.
A deep spectrum taken with the Echelle Spectrograph and Imager (ESI) at the Keck II Telescope as part of the Lenses Structure and Dynamics (LSD) Survey reveals the redshifts of the extremely red source of the radio Einstein ring in the gravitational lens system MG 1549+305 (zs= 1.170 +/- 0.001) and an intermediate-redshift lensed spiral…
A two-arm gaseous spiral in the inner 200 pc of the early-type galaxy NGC 2974: signature of an inner bar
Emsellem, Eric; Ferruit, Pierre; Goudfrooij, Paul
TIGER integral-field spectrography and Hubble Space Telescope Wide Field and Planetary Camera 2 (WFPC2) imaging of the E3 galaxy NGC 2974 are used to derive the kinematics of the stellar and ionized gas components in its central 500 pc. We derive a numerical two-integral distribution function from a multi-Gaussian expansion (MGE) mass model using …
H1320+551: a type 1.8/1.9 Seyfert galaxy with an unabsorbed X-ray spectrum
Barcons, X.; Carrera, F. J.; Ceballos, M. T.
We present new optical spectroscopic and XMM-Newton X-ray observations of the active galactic nucleus (AGN) H1320+551. The optical data (consistent with but of better quality than a previously published spectrum) show this source to be a type 1.8/1.9 Seyfert galaxy at z= 0.0653. The narrow-line region is significantly reddened, with a Balmer decre…
XMM-Newton RGS spectroscopy of LMC X-3
Page, M. J.; Soria, R.; Mason, K. O. +3 more
We present soft X-ray spectroscopy of the black hole binary LMC X-3 from the XMM-Newton Reflection Grating Spectrometer. The observations span the full range of spectral states seen in LMC X-3. The spectra are completely dominated by continuum emission, and the neutral absorbing column measured from the OI edge (NH= 3.8+0.8
The identification of HCN and HNC in carbon stars: model atmospheres, synthetic spectra and fits to observations in the 2.7-4.0 µm region
Jones, H. R. A.; Tennyson, J.; Pavlenko, Ya. V. +1 more
Model carbon star atmospheres and synthetic spectra have been calculated using the recent HCN/HNC vibration rotation line list of Harris et al. The calculations are repeated using only HCN lines and show that HNC has a significant effect upon the temperature, density and optical depth of a stellar atmosphere.
We fit synthetic spectra in the 2…Three-component Stäckel potentials satisfying recent estimates of Milky Way parameters
Famaey, B.; Dejonghe, H.
We present a set of three-component Stäckel potentials defined by five parameters and designed to model the Milky Way. We review the fundamental constraints that any model of the Milky Way must satisfy, including the most recent ones derived from Hipparcos data, and we study how the parameters of the presented potentials can vary in order to match…
The Phoenix Deep Survey: X-ray properties of faint radio sources
Georgakakis, A.; Sullivan, M.; Georgantopoulos, I. +4 more
In this paper, we use a 50-ks XMM-Newton pointing overlapping with the Phoenix Deep Survey, a homogeneous radio survey reaching µJy sensitivities, to explore the X-ray properties and the evolution of star-forming galaxies. Multiwavelength ultraviolet, optical and near-infrared photometric data are available for this field and are used to est…
