Deeper Chandra Follow-up of Cygnus TeV Source Perpetuates Mystery
Yousaf Butt, Jeremy Drake, Paula Benaglia +4
A 50 ksec Chandra observation of the unidentified TeV source in Cygnus reported by the HEGRA collaboration reveals no obvious diffuse X-ray counterpart. However, 240 Pointlike X-ra…
The INT Photometric H-alpha Survey of the Northern Galactic Plane (IPHAS)
Janet E. Drew, R. Greimel, M. J. Irwin +1
The INT Photometric Halpha Survey of the Northern Galactic Plane (IPHAS) is a 1800 square degrees CCD survey of the northern Milky Way spanning the latitude range -5 < b < +5 (degr…
The "Solar Model Problem" Solved by the Abundance of Neon in Stars of the Local Cosmos
Jeremy J. Drake Paola Testa
The interior structure of the Sun can be studied with great accuracy using observations of its oscillations, similar to seismology of the Earth. Precise agreement between helioseis…
Probing the Local Group Medium Toward Mkn 421 with Chandra and FUSE
Rik J. Williams, Smita Mathur, Fabrizio Nicastro +7
We report the detection of highly-ionized gas at z~0 seen in resonant UV and X-ray absorption lines toward the z=0.03 blazar Mkn 421. A total of 13 X-ray and 3 UV lines were measur…
Chandra Detection of the First X-ray Forest along the Line of Sight To Mkn 421
Fabrizio Nicastro, Smita Mathur, Martin Elvis +7
We present the first >=3.5 sigma (conservative) or >=5.8 sigma (sum of lines significance) detection of two Warm-Hot Intergalactic Medium (WHIM) filaments at z>0, which we find alo…
Deposing the Cool Corona of KPD 0005+5106
Jeremy J. Drake, Klaus Werner
The ROSAT PSPC pulse height spectrum of the peculiar He-rich hot white dwarf KPD 0005+5106 provided a great surprise when first analysed by Fleming, Werner & Barstow (1993). It def…
