Spectral Energy Distribution of Markarian 501: Quiescent State vs. Extreme Outburst
The VERITAS Collaboration, V. A. Acciari, T. Arlen +225
The very high energy (VHE; E > 100 GeV) blazar Markarian 501 has a well-studied history of extreme spectral variability and is an excellent laboratory for studying the physical pro…
Characterizing optical chirality
Konstantin Y. Bliokh, Franco Nori
We examine the recently introduced measure of chirality of a monochromatic optical field [Y. Tang and A. E. Cohen, Phys. Rev. Lett. 104, 163901 (2010)] using the momentum (plane-wa…
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…
Homomorphisms between mapping class groups
Javier Aramayona, Juan Souto
Suppose that and are surfaces of finite topological type, where has genus and has genus at most ; in addition, suppose that is not closed if it…
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…
Internal flows and energy circulation in light beams
Aleksandr Bekshaev, Konstantin Bliokh, Marat Soskin
We review optical phenomena associated with the internal energy redistribution which accompany propagation and transformations of monochromatic light fields in homogeneous media. T…
The jet in M87 from EVN observations
G. Giovannini, C. Casadio, M. Giroletti +3
One of the most intriguing open questions of today's astrophysics is the jet physical properties and the location and the mechanisms for the production of MeV, GeV, and TeV gamma-r…
Mimicking the probability distribution of a two-dimensional Grover walk with a single-qubit coin
C. Di Franco, M. McGettrick, Th. Busch
Multi-dimensional quantum walks usually require large coin spaces. Here we show that the non-localized case of the spatial density probability of the two-dimensional Grover walk ca…
Modelling the radio pulses of an ultracool dwarf
S. Yu, G. Hallinan, J. G. Doyle +5
Recently unanticipated magnetic activity in ultracool dwarfs (UCDs, spectral classes later than M7) have emerged from a number of radio observations. The highly (up to 100%) circul…
The 2008 Outburst in the Young Stellar System Z CMa: The First Detection of Twin Jets
Emma Whelan, Catherine Dougados, Marshall Perrin +11
The Z CMa binary is understood to undergo both FU Orionis (FUOR) and EX Orionis (EXOR) type outbursts. While the SE component has been spectro- scopically identified as an FUOR, th…
Genus Two Partition and Correlation Functions for Fermionic Vertex Operator Superalgebras I
Michael P. Tuite, Alexander Zuevsky
We define the partition and -point correlation functions for a vertex operator superalgebra on a genus two Riemann surface formed by sewing two tori together. For the free fermi…
Towards an explanation for the 30 Dor (LMC) Honeycomb nebula - the impact of recent observations and spectral analysis
John Meaburn, Matt P. Redman, Panos Boumis +1
The unique Honeycomb nebula, most likely a peculiar supernova remnant, lies in 30 Doradus in the Large Magellanic Cloud. Due to its proximity to SN1987A, it has been serendipitousl…
VERITAS Search for VHE Gamma-ray Emission from Dwarf Spheroidal Galaxies
The VERITAS Collaboration, V. A. Acciari, T. Arlen +73
Indirect dark matter searches with ground-based gamma-ray observatories provide an alternative for identifying the particle nature of dark matter that is complementary to that of d…
Can the Renormalization Group Improved Effective Potential be used to estimate the Higgs Mass in the Conformal Limit of the Standard Model?
F. A. Chishtie, T. Hanif, J. Jia +4
We consider the effective potential in the standard model with a single Higgs doublet in the limit that the only mass scale present is radiatively generated. Using a techni…
Angular Momenta and Spin-Orbit Interaction of Nonparaxial Light in Free Space
K. Y. Bliokh, M. A. Alonso, E. A. Ostrovskaya +1
We give an exact self-consistent operator description of the spin and orbital angular momenta, position, and spin-orbit interactions of nonparaxial light in free space. Both quantu…
Dark spot, Spiral waves and the SW Sex behaviour: it is all about UX Ursae Majoris
V. V. Neustroev, V. F. Suleimanov, N. V. Borisov +2
We present an analysis of time-resolved, medium resolution optical spectroscopic observations of UX UMa in the blue (3920-5250 A) and red (6100-7200 A) wavelength ranges, that were…

The VERITAS Collaboration, V. A. Acciari, E. Aliu +84
M87 is a nearby radio galaxy that is detected at energies ranging from radio to VHE gamma-rays. Its proximity and its jet, misaligned from our line-of-sight, enable detailed morpho…
