Valley Degeneracies in (111) Silicon Quantum Wells
Neerav Kharche, Seongmin Kim, Timothy B. Boykin +1
(111) Silicon quantum wells have been studied extensively, yet no convincing explanation exists for the experimentally observed breaking of 6 fold valley degeneracy into 2 and 4 fo…
Active Galactic Nuclei: Sources for ultra high energy cosmic rays?
P. L. Biermann, J. K. Becker, L. Caramete +11
The origin of ultra high energy cosmic rays promises to lead us to a deeper understanding of the structure of matter. This is possible through the study of particle collisions at c…
Ground-based calibration and characterization of the Fermi Gamma-Ray Burst Monitor Detectors
Elisabetta Bissaldi, Andreas von Kienlin, Giselher G. Lichti +18
One of the scientific objectives of NASA's Fermi Gamma-ray Space Telescope is the study of Gamma-Ray Bursts (GRBs). The Fermi Gamma-Ray Burst Monitor (GBM) was designed to detect a…
Evolution of Anemone AR NOAA 10798 and the Related Geo-Effective Flares and CMEs
Ayumi Asai, Kazunari Shibata, Takako T. Ishii +4
We present a detailed examination of the features of the Active Region (AR) NOAA 10798. This AR generated coronal mass ejections (CMEs) that caused a large geomagnetic storm on 24…
Black hole quasinormal mode spectroscopy with LISA
Manish M. Jadhav, Lior M. Burko
The signal-to-noise ratio (SNR) for black hole quasinormal mode sources of low-frequency gravitational waves is estimated using a Monte Carlo approach that replaces the all-sky ave…
Local times of multifractional Brownian sheets
Mark Meerschaert, Dongsheng Wu, Yimin Xiao
Denote by a function in with values in . Let be an -multifr…
The Heliosphere in Time
H. -R. Müller, P. C. Frisch, B. D. Fields +1
Because of the dynamic nature of the interstellar medium, the Sun should have encountered a variety of different interstellar environments in its lifetime. As the solar wind intera…
No observational constraints from hypothetical collisions of hypothetical dark halo primordial black holes with galactic objects
Marek A. Abramowicz, Julia K. Becker, Peter L. Biermann +3
It was suggested by several authors that hypothetical primordial black holes (PBHs) may contribute to the dark matter in our Galaxy. There are strong constraints based on the Hawki…
Upward and Downward Runs on Partially Ordered Sets
Kyle Siegrist
We consider Markov chains on partially ordered sets that generalize the success-runs and remaining life chains in reliability theory. We find conditions for recurrence and transien…
Constant Rate Distributions on Partially Ordered Sets
Kyle Siegrist
We consider probability distributions with constant rate on partially ordered sets, generalizing distributions in the usual reliability setting that have constant failure rate. In…
A Study of the X-Ray Dust Scattering Halo of Cyg X-1 with a Cross-Correlation Method
Zhixing Ling, Shuang Nan Zhang, Jingen Xiang +1
X-ray photons scattered by the interstellar medium carry information about dust distribution, dust grain model, scattering cross section, and the distance of the source; they also…
Limits on CO2 Climate Forcing from Recent Temperature Data of Earth
David H. Douglass, John R. Christy
The global atmospheric temperature anomalies of Earth reached a maximum in 1998 which has not been exceeded during the subsequent 10 years. The global anomalies are calculated from…
Application of a Self-Similar Pressure Profile to Sunyaev-Zel'dovich Effect Data from Galaxy Clusters
T. Mroczkowski, M. Bonamente, J. E. Carlstrom +16
We investigate the utility of a new, self-similar pressure profile for fitting Sunyaev-Zel'dovich (SZ) effect observations of galaxy clusters. Current SZ imaging instruments - such…
Joint continuity of the local times of fractional Brownian sheets
Antoine Ayache, Dongsheng Wu, Yimin Xiao
Let be an -fractional Brownian sheet with index defined by $B^H(t)=(B^H_1(t),...,B^H_d(t)) (t\in {\mathbb{R…
Reconstructing the Cosmic Expansion History up to Redshift z=6.29 with the Calibrated Gamma-Ray Bursts
Hao Wei, Shuang Nan Zhang
Recently, Gamma-Ray Bursts (GRBs) were proposed to be a complementary cosmological probe to type Ia supernovae (SNIa). GRBs have been advocated to be standard candles since several…
Magnetic Reconnection by a Self-Retreating X-Line
M. Oka, M. Fujimoto, T. K. M. Nakamura +2
Particle-in-cell (PIC) simulations of collisionless magnetic reconnection are performed to study asymmetric reconnection in which an outflow is blocked by a hard wall while leaving…
T-Lyr1-17236: A Long-Period Low-Mass Eclipsing Binary
Jonathan Devor, David Charbonneau, Guillermo Torres +8
We describe the discovery of a 0.68+0.52 solar mass eclipsing binary (EB) with an 8.4-day orbital period, found through a systematic search of ten fields of the Trans-atlantic Exop…
Energy Cascades in Astrophysical Plasma
Dastgeer Shaikh, Gary P. Zank
A local turbulence model is developed to study energy cascades in the interstellar medium (ISM) based on self-consistent two-dimensional fluid simulations. The model describes a pa…
3D Electron Fluid Turbulence at Nanoscales in Dense Plasmas
Dastgeer Shaikh, P. K. Shukla
We have performed three dimensional nonlinear fluid simulations of electron fluid turbulence at nanoscales in an unmagnetized warm dense plasma in which mode coupling between wave…
Evidence for an intermediate line region in AGN's inner torus region and its evolution from narrow to broad line Seyfert I galaxies
Ling Zhu, Shuang Nan Zhang, Sumin Tang
A two-components model for Broad Line Region (BLR) of Active Galactic Nuclei (AGN) has been suggested for many years but not widely accepted (e.g., Hu et al. 2008; Sulentic et al.…
Debye relaxation in high magnetic fields
J. S. Brooks, R. Vasic, A. Kismarahardja +4
Dielectric relaxation is universal in characterizing polar liquids and solids, insulators, and semiconductors, and the theoretical models are well developed. However, in high magne…
