First HARPSpol discoveries of magnetic fields in massive stars
E. Alecian, O. Kochukhov, C. Neiner +14
In the framework of the Magnetism in Massive Stars (MiMeS) project, a HARPSpol Large Program at the 3.6m-ESO telescope has recently started to collect high-resolution spectropolari…
Characterizing the magnetic fields of the first tau Sco analogues
V. Petit, O. Kochukhov, D. L. Massa +3
The B0.2 V magnetic star tau Sco stands out from the larger population of massive OB stars due to its high X-ray activity, peculiar wind diagnostics and complex magnetic field. Rec…
The spectral variability and magnetic field characteristics of the Of?p star HD 148937
G. A. Wade, J. Grunhut, G. Graefener +11
We report magnetic and spectroscopic observations and modeling of the Of?p star HD 148937 within the context of the MiMeS LP at the CFHT. Thirty-two high signal-to-noise ratio circ…
HR 5907: Discovery of the most rapidly rotating magnetic B-type star by the MiMeS Collaboration
J. H. Grunhut, Th. Rivinius, G. A. Wade +15
We report the discovery and analysis of a very strong magnetic field in the rapidly rotating early B-type star HR 5907, based on observations obtained as part of the Magnetism in M…
The Atacama Cosmology Telescope: High-Resolution Sunyaev-Zel'dovich Array Observations of ACT SZE-selected Clusters from the Equatorial Strip
Erik D. Reese, Tony Mroczkowski, Felipe Menanteau +41
We present follow-up observations with the Sunyaev-Zel'dovich Array (SZA) of optically-confirmed galaxy clusters found in the equatorial survey region of the Atacama Cosmology Tele…
The Atacama Cosmology Telescope: a measurement of the primordial power spectrum
Renée Hlozek, Joanna Dunkley, Graeme Addison +37
We present constraints on the primordial power spectrum of adiabatic fluctuations using data from the 2008 Southern Survey of the Atacama Cosmology Telescope (ACT). The angular res…
A Chandra Observation of the TW Hydrae Association Brown Dwarf 2MASSW J1139511-315921
Philip J. Castro, John E. Gizis, Marc Gagné
We report on a sequence of Chandra X-ray Observatory observations of the TW Hydrae brown dwarf (BD) 2MASSW J1139511-315921 (2M1139). In the combined 31 ks ACIS-S exposure, 2M1139 i…
Evidence for dark energy from the cosmic microwave background alone using the Atacama Cosmology Telescope lensing measurements
Blake D. Sherwin, Joanna Dunkley, Sudeep Das +35
For the first time, measurements of the cosmic microwave background radiation (CMB) alone favor cosmologies with dark energy over models without dark energy at a 3.2-sigma l…
Chandra X-ray spectroscopy of the very early O supergiant HD 93129A: constraints on wind shocks and the mass-loss rate
David H. Cohen, Marc Gagné, Maurice A. Leutenegger +5
We present analysis of both the resolved X-ray emission line profiles and the broadband X-ray spectrum of the O2 If* star HD 93129A, measured with the Chandra HETGS. This star is a…
Tracing the Energetics and Evolution of Dust with Spitzer: a Chapter in the History of the Eagle Nebula
N. Flagey, F. Boulanger, A. Noriega-Crespo +5
The Spitzer GLIMPSE and MIPSGAL surveys have revealed a wealth of details of the Galactic plane. We use them to study the energetics and dust properties of M16, one of the best kno…
The Search for Low-mass Companions of B Stars in the Carina Nebula Cluster Trumpler 16
Nancy Remage Evans, Kathleen DeGioia-Eastwood, Marc Gagne +9
We have developed lists of likely B3--A0 stars (called "late B" stars) in the young cluster Trumpler 16. The following criteria were used: location within 3' of Eta Car, an appropr…
Carina OB Stars: X-ray Signatures of Wind Shocks and Magnetic Fields
Marc Gagne, Garrett Fehon, Michael R. Savoy +10
The Chandra Carina Complex contains 200 known O- and B type stars. The Chandra survey detected 68 of the 70 O stars and 61 of 127 known B0-B3 stars. We have assembled a publicly av…
The Chandra Carina Complex Project: Deciphering the Enigma of Carina's Diffuse X-ray Emission
Leisa K. Townsley, Patrick S. Broos, You-Hua Chu +11
We present a 1.42 square degree mosaic of diffuse X-ray emission in the Great Nebula in Carina from the Chandra X-ray Observatory Advanced CCD Imaging Spectrometer camera. After re…
Detection of the Power Spectrum of Cosmic Microwave Background Lensing by the Atacama Cosmology Telescope
Sudeep Das, Blake D. Sherwin, Paula Aguirre +38
We report the first detection of the gravitational lensing of the cosmic microwave background through a measurement of the four-point correlation function in the temperature maps m…
Global X-ray properties of the O and B stars in Carina
Y. Naze, P. S. Broos, L. Oskinova +10
The key empirical property of the X-ray emission from O stars is a strong correlation between the bolometric and X-ray luminosities. In the framework of the Chandra Carina Complex…
