IPHAS discoveries of young stars towards Cyg OB2 and its southern periphery (2008)
Vink, Jorick S., Drew, Janet E., Steeghs, Danny, Wright, Nick J., Martin, Eduardo L., Gaensicke, Boris T., ...
We report on the discovery of over 50 strong Halpha emitting objects towards the large OB association Cyg OB2 and the HII region DR 15 on its southern periphery. This was achieved using the INT...

TeV J2032+4130: a not-so-dark Accelerator? (2006)
Butt, Yousaf M., Combi, Jorge A., Drake, Jeremy, Finley, John P., Konopelko, Alexander, Lister, Matthew, ...
The HEGRA gamma-ray source TeV J2032+4130 is considered the prototypical 'dark accelerator', since it was the first TeV source detected with no firm counterparts at lower frequencies. The Whipple...
Deeper Chandra Follow-up of Cygnus TeV Source Perpetuates Mystery (2005)
Butt, Yousaf, Drake, Jeremy, Benaglia, Paula, Combi, Jorge, Dame, Thomas, Miniati, Francesco, ...
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-ray sources are...
Chandra Detection of the First X-ray Forest along the Line of Sight To Mkn 421 (2005)
Nicastro, Fabrizio, Mathur, Smita, Elvis, Martin, Drake, Jeremy, Fiore, Fabrizio, Fang, Taotao, ...
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 along the line of...
Cosmic Ray Acceleration by Stellar Associations? The Case of Cygnus OB2 (2003)
Butt, Yousaf, Benaglia, Paula, Combi, Jorge, Corcoran, Michael, Dame, Thomas, Drake, Jeremy, ...
The origins of all extra-solar cosmic rays -- both the ultra high-energy and lower energy Galactic variety -- remain unclear. It has been argued that the large scale shocks and turbulence induced by...
CHANDRA/VLA Follow-up of TeV J2032+4131, the Only Unidentified TeV Gamma-ray Source (2003)
Butt, Yousaf, Benaglia, Paula, Combi, Jorge, Corcoran, Michael, Dame, Thomas, Drake, Jeremy, ...
The HEGRA Cherenkov telescope array group recently reported a steady and extended unidentified TeV gamma-ray source lying at the outskirts of Cygnus OB2. This is the most massive stellar association...
Chandra Multi-wavelength Plane (ChaMPlane) Survey: Design and Initial Results (2002)
Grindlay, Jonathan, Zhao, Ping, Hong, JaeSub, Jenkins, Johnathan, Kim, Dong-Woo, Schlegel, Eric, ...
The Chandra Multiwavength Plane (ChaMPlane) Survey of the galactic plane incorporates serendipitous sources from selected Chandra pointings in or near the galactic plane (b < 12deg; >20 ksec; lack of...
Flare Heating in Stellar Coronae (2002)
Kashyap, Vinay, Drake, Jeremy, Guedel, Manuel, Audard, Marc
We investigate the contribution of very weak flares to the coronal luminosity of low-mass active stars. We analyze EUVE/DS events data from FK Aqr, V1054 Oph, and AD Leo and conclude that in all...
Bayesian Spectral Analysis of Metal Abandance Deficient Stars (2002)
Sourlas, Epaminondas, Van Dyk, David, Kashyap, Vinay, Drake, Jeremy, Pease, Deron
Metallicity can be measured by analyzing the spectra in the X-ray region and comparing the flux in spectral lines to the flux in the underlying Bremsstrahlung continuum. In this paper we propose new...
CHANDRA, EUVE, HST, and VLA Multiwavelength . . . . (2001)
Thomas Ayres, Alexander Brown, Rachel Osten, David Huenemoerder, Jeremy Drake, Jeffrey Linsky
In mid-September of 1999, a multiwavelength campaign was carried out on the coronally active RS Canum Venaticorum binary HR 1099 (K1 IV ]G5 V ; P 2.84 days), during commissioning of the High Energy...
On X-ray Variability in Active Binary Stars (1999)
We compare the count-rates of active binaries observed by Einstein and ROSAT. We find significant evidence for short-term variability (approx 0.32) and marginal evidence for a larger variability at...
