Section on Extragalactic Science Topics of the White Paper on the Status and Future of Ground-Based TeV Gamma-Ray Astronomy
H. Krawczynski, A. M. Atoyan, M. Beilicke +32
This is a report on the findings of the extragalactic science working group for the white paper on the status and future of TeV gamma-ray astronomy. The white paper was commissione…
A search for a counterpart of the unidentified gamma-ray source 3EG J2020+4017 (2CG078+2)
Martin C. Weisskopf, Douglas A. Swartz, Alberto Carraminana +7
We report observations with the Chandra X-ray Observatory of a field in the gamma$-Cygni supernova remnant (SNR78.2+2.1) centered on the cataloged location of the unidentified, bri…
High altitude wind velocity at Sierra Negra and San Pedro Mártir
Esperanza Carrasco, Remy Avila, Alberto Carramiñana
It has been proposed that the global circulation of the atmosphere winds at 200 mb can be used as a criteria to establish the suitability of a site for the development of adaptive…
Spectroscopy and 3D imaging of the Crab nebula
Andrej Cadez, Alberto Carraminana, Simon Vidrih
Spectroscopy of the Crab nebula along different slit directions reveals the 3 dimensional structure of the optical nebula. On the basis of the linear radial expansion result first…
The European Large Area ISO Survey IX: the 90 micron luminosity function from the Final Analysis sample
S. Serjeant, A. Carraminana, E. Gonzales-Solares +18
We present the 90 micron luminosity function of the Final Analysis of the European Large Area ISO Survey (ELAIS), extending the sample size of our previous analysis (paper IV) by a…
Monopolar Pulsar Spin-Down
Cesar Alvarez, Alberto Carramiñana
A multipole spin-down equation based on a monopolar term is derived from the general expression and used to study pulsar evolution. We show that the time-independ…
The European Large Area ISO Survey (ELAIS): The Final Band-merged Catalogue
ELAIS Consortium, :, M. Rowan-Robinson +16
We present the final band-merged ELAIS catalogue at 6.7, 15, 90, and 175 m, and the associated data at u,g,r,i,z,J,H,K, and 20cm. The origin of the survey, infrared and radio ob…
Optical Seeing at Sierra Negra
Esperanza Carrasco, Alberto Carraminana, Jose Luis Aviles +1
Optical seeing measurements carried out at Sierra Negra, the site of the Large Millimeter Telescope, are reported. The site, one of the highest peaks of Central Mexico, offers good…
Multifrequency studies of the enigmatic gamma-ray source 3EG J1835+5918
O. Reimer, K. T. S. Brazier, A. Carraminana +3
The EGRET telescope has repeatedly observed 3EG J1835+5918 as a bright and steady source of high-energy gamma-ray radiation which has not yet been indentified. EGRET data from CGRO…
ASCA and other contemporaneous observations of the blazar B2 1308+326
D. Watson, N. Smith, L. Hanlon +8
The high redshift (z=0.997) blazar B2 1308+326 was observed contemporaneously at x-ray, optical and radio wavelengths in June 1996. The x-ray observations were performed with ASCA.…
Optical Spectrum of Main-, Inter- and Off-pulse Emission from Crab Pulsar
Alberto Carraminana, Andrej Cadez, Tomaz Zwitter
A dedicated stroboscopic device was used to obtain optical spectra of the Crab main-pulse and inter-pulse as well as the spectrum of the underlying nebula when the pulsar is turned…
The PSCz Catalogue
W. Saunders, W. J. Sutherland, S. J. Maddox +10
We present the catalogue, mask, redshift data and selection function for the PSCz survey of 15411 IRAS galaxies across 84% of the sky. Most of the IRAS data is taken from the Point…
The PSCz catalogue
Will Saunders, Seb Oliver, Oliver Keeble +8
We present the catalogue and redshift data for the PSCz survey of 15,000 IRAS galaxies over 84% of the sky. The uniformity, completeness and data quality are assessed, and guidelin…
COMPTEL detection of pulsed gamma-ray emission from B1509-58 up to at least 10 MeV
L. Kuiper, W. Hermsen, J. M. Krijger +5
We report on the first firm detection of pulsed gamma-ray emission from PSR B1509-58 in the 0.75-30 MeV energy range in CGRO COMPTEL data collected over more than 6 years. The modu…
Comptel Detection of Pulsed Emission from PSR B1509-58 up to at Least 10 MeV
L. Kuiper, W. Hermsen, J. M. Krijger +5
We report the COMPTEL detection of pulsed -emission from PSR B1509-58 up to at least 10 MeV using data collected over more than 6 years. The 0.75-10 MeV lightcurve is broad and…
Diffuse Gamma-Ray Emission from Starburst Galaxies and M31
Jan J. Blom, Timothy A. D. Paglione, Alberto Carraminana
We present a search for high energy gamma-ray emission from 9 nearby starburst galaxies and M31 with the EGRET instrument aboard CGRO. Though the diffuse gamma-ray emission from st…
