SPH Simulations of Direct Impact Accretion in the Ultracompact AM CVn Binaries
The ultracompact binary systems V407 Vul (RX J1914.4+2456) and HM Cnc (RX J0806.3+1527), a two-member subclass of the AM CVn stars, continue to generate interest because they defy unambiguous classification. Three proposed ...
Commentary on "Mounds from the Merin lagoon basin: Time, space and society"(Review) [Comentario sobre "Montículos de la cuenca de la laguna Merín: Tiempo, espacio, y sociedad"]
In the appendix of his recent paper, Bracco (2006:511-540) made several comments and misinterpretations regarding the interdisciplinary scientific evidence produced by our team at the Los Ajos site in southeastern Uruguay. ...
A Novel Method for Measuring the Extragalactic Background Light: Fermi Application to the Lobes of Fornax A
We describe a new method for measuring the extragalactic background light (EBL) through the detection of γ-ray inverse Compton (IC) emission due to scattering of the EBL photons off relativistic electrons in the lobes of ...
New retarded integral inequalities with applications
Some new nonlinear integral inequalities of Gronwall type for retarded functions are established, which extend the results Lipovan (2003) and Pachpatte (2004). These inequalities can be used as basic tools in the study of ...
New integral inequalities for iterated integrals with applications
Some new nonlinear retarded integral inequalities of Gronwall type are established. These inequalities can be used as basic tools in the study of certain classes of integrodifferential equations.
Orbital parameters and chemical composition of four white dwarfs in post-common-envelope binaries
We present FUSE observations of the hot white dwarfs in the post-common-envelope binaries Feige 24, EUVE J0720-317, BPM 6502, and EUVE J2013+400. The spectra show numerous photospheric absorption lines, which trace the ...
Time evolution of terrestrial gamma ray flashes
We present a study of the time evolution of TGFs observed by both RHESSI and BATSE and compare the data with Monte Carlo simulations of relativistic runaway electron avalanches that record the time of flight for individual ...
The pulsating DA white dwarf star EC 14012−1446: results from four epochs of time-resolved photometry
The pulsating DA white dwarfs are the coolest degenerate stars that undergo self-driven oscillations. Understanding their interior structure will help us to understand the previous evolution of the star. To this end, we ...
Suppression pattern of neutral pions at high transverse momentum in Au+Au collisions at sNN=200GeV and constraints on medium transport coefficients
For Au+Au collisions at 200 GeV, we measure neutral pion production with good statistics for transverse momentum, pT, up to 20GeV/c. A fivefold suppression is found, which is essentially constant for 5<pT<20GeV/c. Experimental ...
Science of Active Galactic Nuclei with the GTC and CanariCam
CanariCam is the facility mid-infrared (MIR) instrument for the Gran Telescopio Canarias (GTC), a 10.4m telescope at the Observatorio del Roque de los Muchachos on La Palma. One of the science drivers for CanariCam is the ...
