Radio and Gamma-Ray Constraints on the Emission Geometry and Birthplace of PSR J2043+2740
A. Noutsos, A. A. Abdo, M. Ackermann +146
We report on the first year of Fermi gamma-ray observations of pulsed high-energy emission from the old PSR J2043+2740. The study of the gamma-ray efficiency of such old pulsars gi…
MESS (Mass-loss of Evolved StarS), a Herschel Key Program
M. A. T. Groenewegen, C. Waelkens, M. J. Barlow +39
MESS (Mass-loss of Evolved StarS) is a Guaranteed Time Key Program that uses the PACS and SPIRE instruments on board the Herschel Space Observatory to observe a representative samp…
Fermi Large Area Telescope observations of Local Group galaxies: Detection of M31 and search for M33
LAT collaboration
Cosmic rays (CRs) can be studied through the galaxy-wide gamma-ray emission that they generate when propagating in the interstellar medium. The comparison of the diffuse signals fr…
Insights Into the High-Energy Gamma-ray Emission of Markarian 501 from Extensive Multifrequency Observations in the Fermi Era
LAT collaboration, A. A. Abdo et al., the MAGIC collaboration +6
We report on the gamma-ray activity of the blazar Mrk 501 during the first 480 days of Fermi operation. We find that the average LAT gamma-ray spectrum of Mrk 501 can be well descr…
A New Frequency-Luminosity Relation for Long GRBs?
T. N. Ukwatta, K. S. Dhuga, D. C. Morris +7
We have studied power density spectra (PDS) of 206 long Gamma-Ray Bursts (GRBs). We fitted the PDS with a simple power-law and extracted the exponent of the power-law (alpha) and t…
Fermi-LAT Search for Pulsar Wind Nebulae around gamma-ray Pulsars
The Fermi LAT Collaboration, Pulsar Timing Consortium
The high sensitivity of the Fermi-LAT (Large Area Telescope) offers the first opportunity to study faint and extended GeV sources such as pulsar wind nebulae (PWNe). After one year…
Hilbert Space Representations of Decoherence Functionals and Quantum Measures
Stan Gudder
We show that any decoherence functional can be represented by a spanning vector-valued measure on a complex Hilbert space. Moreover, this representation is unique up to an isom…
Multi-wavelength Observations of the Flaring Gamma-ray Blazar 3C 66A in 2008 October
LAT collaboration, A. A. Abdo et al., the VERITAS collaboration +4
The BL Lacertae object 3C 66A was detected in a flaring state by the Fermi Large Area Telescope (LAT) and VERITAS in 2008 October. In addition to these gamma-ray observations, F-GA…
Constraints on the Cosmic-Ray Density Gradient beyond the Solar Circle from Fermi gamma-ray Observations of the Third Galactic Quadrant
Fermi LAT Collaboration
We report an analysis of the interstellar -ray emission in the third Galactic quadrant measured by the {Fermi} Large Area Telescope. The window encompassing the Galactic plane f…
Gamma-ray flares from the Crab Nebula
LAT Collaboration
A young and energetic pulsar powers the well-known Crab Nebula. Here we describe two separate gamma-ray (photon energy >100 MeV) flares from this source detected by the Large Area…
Search for gamma-ray emission from magnetars with the Fermi Large Area Telescope
LAT collaboration
We report on the search for 0.1-10 GeV emission from magnetars in 17 months of Fermi Large Area Telescope (LAT) observations. No significant evidence for gamma-ray emission from an…
Ergodic Actions of Convergent Fuchsian groups on quotients of the noncommutative Hardy algebras
Alvaro Arias, Frederic Latremoliere
We establish that particular quotients of the non-commutative Hardy algebras carry ergodic actions of convergent discrete subgroups of the group of automo…
Symmetry in the Cuntz Algebra on two generators
Man-Duen Choi, Frederic Latremoliere
We investigate the structure of the automorphism of which exchanges the two canonical isometries. Our main observation is that the fixed point C*-subalgebra for t…
Low-threshold analysis of CDMS shallow-site data
CDMS Collaboration, D. S. Akerib, M. J. Attisha +45
Data taken during the final shallow-site run of the first tower of the Cryogenic Dark Matter Search (CDMS II) detectors have been reanalyzed with improved sensitivity to small ener…
The Universe and The Quantum Computer
Stan Gudder
It is first pointed out that there is a common mathematical model for the universe and the quantum computer. The former is called the histories approach to quantum mechanics and th…
Detection of 16 Gamma-Ray Pulsars Through Blind Frequency Searches Using the Fermi LAT
LAT Collaboration
Pulsars are rapidly-rotating, highly-magnetized neutron stars emitting radiation across the electromagnetic spectrum. Although there are more than 1800 known radio pulsars, until r…
Time-division SQUID multiplexers with reduced sensitivity to external magnetic fields
G. M. Stiehl, H. M. Cho, G. C. Hilton +4
Time-division SQUID multiplexers are used in many applications that require exquisite control of systematic error. One potential source of systematic error is the pickup of externa…
Fermi Large Area Telescope Observation of a Gamma-ray Source at the Position of Eta Carinae
The Fermi LAT collaboration
The Large Area Telescope (LAT) onboard the Fermi Gamma-ray Space Telescope detected a gamma-ray source that is spatially consistent with the location of Eta Carinae. This source ha…
