The enigmatic nature of the circumstellar envelope and bow shock surrounding Betelgeuse as revealed by Herschel. I. Evidence of clumps, multiple arcs, and a linear bar-like structure
L. Decin, N. L. J. Cox, P. Royer +13
Context. The interaction between stellar winds and the interstellar medium (ISM) can create complex bow shocks. The photometers on board the Herschel Space Observatory are ideally…
A note on the Relationship between Localization and Norm-1 Property
Roberto Beneduci, Franklin E. Schroeck
The paper focuses on the problem of localization in quantum mechanics. It is well known that it is not possible to define a localization observable for the photon by means of proje…
Remote Observatory for Variable Object Research (ROVOR)
J. W. Moody, B. Boizelle, K. Bates +8
Observatories constructed solely for photometric monitoring make it possible to understand the temporal nature of objects over time scales that historically have been difficult to…
The Imprint of The Extragalactic Background Light in the Gamma-Ray Spectra of Blazars
LAT Collaboration
The light emitted by stars and accreting compact objects through the history of the Universe is encoded in the intensity of the extragalactic background light (EBL). Knowledge of t…
A commutant realization of Odake's algebra
Thomas Creutzig, Andrew R. Linshaw
The bcβγ-system W of rank 3 has an action of the affine vertex algebra V_0(sl_2), and the commutant vertex algebra C =Com(V_0(sl_2), W) contains copies of V_{-3/2}(sl_2) and Odake'…
The super W_{1+\infty} algebra with integral central charge
Thomas Creutzig, Andrew R. Linshaw
The Lie superalgebra SD of regular differential operators on the super circle has a universal central extension \hat{SD}. For each c\in C, the vacuum module M_c(\hat{SD}) of centra…
The Causal Poset is Directed but not Lattice Ordered
Stanley P Gudder
In the causal set approach to discrete quantum gravity the universe grows one element at a time in discrete steps. At each step the process has the form of a causal set (causet) an…
Fermi LAT study of cosmic-rays and the interstellar medium in nearby molecular clouds
LAT collaboration
We report an analysis of the interstellar gamma-ray emission from the Chamaeleon, R Coronae Australis (R CrA), and Cepheus and Polaris flare regions with the Fermi Large Area Teles…
Gamma-ray observations of the Orion Molecular Clouds with the Fermi Large Area Telescope
M. Ackermann, M. Ajello, A. Allafort +142
We report on the gamma-ray observations of giant molecular clouds Orion A and B with the Large Area Telescope (LAT) on-board the Fermi Gamma-ray Space Telescope. The gamma-ray emis…
An independent distance estimate to CW Leo
M. A. T. Groenewegen, M. J. Barlow, J. A. D. L. Blommaert +13
CW Leo has been observed six times between October 2009 and June 2012 with the SPIRE instrument on board the Herschel satellite. Variability has been detected in the flux emitted b…
Torsors and ternary Moufang loops arising in projective geometry
Wolfgang Bertram, Michael Kinyon
We give an interpretation of the construction of torsors from preceding work (Bertram, Kinyon: Associative Geometries. I, J. Lie Theory 20) in terms of classical projective geometr…
The Fermi Large Area Telescope On Orbit: Event Classification, Instrument Response Functions, and Calibration
LAT Collaboration
The Fermi Large Area Telescope (Fermi-LAT, hereafter LAT), the primary instrument on the Fermi Gamma-ray Space Telescope (Fermi) mission, is an imaging, wide field-of-view, high-en…
The Chandra X-ray Survey of Planetary Nebulae (ChanPlaNS): Probing Binarity, Magnetic Fields, and Wind Collisions
J. H. Kastner, R. Montez, B. Balick +23
We present an overview of the initial results from the Chandra Planetary Nebula Survey (ChanPlaNS), the first systematic (volume-limited) Chandra X-ray Observatory survey of planet…
Fermi LAT Search for Dark Matter in Gamma-ray Lines and the Inclusive Photon Spectrum
LAT Collaboration, M. Ackermann, M. Ajello +117
Dark matter particle annihilation or decay can produce monochromatic gamma-ray lines and contribute to the diffuse gamma-ray background. Flux upper limits are presented for gamma-r…
Stellar Polarimetry: Where Are We and Where Are We Going?
Jennifer L. Hoffman, John C. Brown, Kenneth Nordsieck +2
On the final day of the Stellar Polarimetry conference, participants split up into three "breakout sessions" to discuss the future of the field in the areas of instrumentation, upc…
Constraints on the Galactic Halo Dark Matter from Fermi-LAT Diffuse Measurements
LAT collaboration, M. Ackermann, M. Ajello +139
We have performed an analysis of the diffuse gamma-ray emission with the Fermi Large Area Telescope in the Milky Way Halo region searching for a signal from dark matter annihilatio…
The structure of the Kac-Wang-Yan algebra
Andrew R. Linshaw
The Lie algebra of regular differential operators on the circle has a universal central extension . The invariant subalgebra …
Causal set approach to discrete quantum gravity
Stan Gudder
We begin by describing a sequential growth model in which the universe grows one element at a time in discrete time steps. At each step, the process has the form of a causal set an…
An Einstein equation for discrete quantum gravity
Stan Gudder
The basic framework for this article is the causal set approach to discrete quantum gravity (DQG). Let be the collection of causal sets with cardinality not greater than …
A Matter of Matter and Antimatter
Stan Gudder
A discrete quantum gravity model given by a quantum sequential growth process (QSGP) is considered. The QSGP describes the growth of causal sets (causets) one element at a time in…
Classification of Noncommutative Domain Algebras
Alvaro Arias, Frederic Latremoliere
Noncommutative domain algebras are noncommutative analogues of the algebras of holomorphic functions on domains of $\C^n$ defined by holomorphic polynomials, and they generalize th…
