We present here results obtained from a detailed timing and spectral analysis of three BeppoSAX observations of the binary X-ray pulsar GX 1+4 carried out in August 1996, March 1997, and August 2000. In the middle of the August 2000 observation, the source was in a rare low intensity state that lasted for about 30 hours. Though the source does not show pulsations in the soft X-ray band (1.0–5.5...
An exceptionally intense gamma-ray burst, GRB030329, was detected and localized by the instruments on board the High Energy Transient Explorer satellite (HETE) at 11:37:14 UT on 29 March 2003. The burst consisted of two ∼10s pulses of roughly equal brightness and an X-ray tail lasting >100s. The energy Center for Space Research, Massachusetts Institute of Technology, 70 Vassar Street, Cambridge...
We present results obtained from three BeppoSAX observations of the accretion-powered transient X-ray pulsar KS 1947+300 carried out during the declining phase of its 2000 November – 2001 June outburst. A detailed spectral study of KS 1947+300 across a wide X-ray band (0.1–100.0 keV) is attempted for the first time here. Timing analysis of the data clearly shows a 18.7 s pulsation in the X-ray ...
The Supersymmetry Les Houches Accord (SLHA) [1] provides a universal set of conventions for conveying spectral and decay information for supersymmetry analysis problems in high energy physics. Here, we propose extensions of the conventions of the first SLHA to include various generalisations: the minimal supersymmetric standard model with violation of CP, R-parity, and flavour, as well as the s...
We report the results of spectral and morphological studies of X-ray data from the supernova remnant (SNR) W44. Spectral analysis of archival data from the Einstein Observatory, ROSAT, and Ginga, covering a total energy range from 0.3 to 8 keV, indicates that the SNR can be described well by a nonequilibrium ionization (NEI) model with temperature ∼0.9 keV and ionization timescale of order 6000...
The abelian sandpile models feature a finite abelian group G generated by the operators corresponding to particle addition at various sites. We study the canonical decomposition of G as a product of cyclic groups G = Zd1 ×Zd2 ×Zd3 · · ·×Zdg where g is the least number of generators of G, and di is a multiple of di+1. The structure of G is determined in terms of the toppling matrix ∆. We constru...
Procedures for correcting the beam-beam effects in luminosity measurement at CLIC at 3 TeV CM energy are described and tested using Monte Carlo simulations: • Correction of the angular counting loss due to the combined Beamstrahlung and initial-state radiation (ISR) effects, based on the reconstructed velocity of the collision frame of the Bhabha scattering. • Deconvolution of the luminosity sp...

In this chapter we use the epistemology of the third space developed by Bhabha (1994) and extended by Frenkel (2008) along with Bhabha’s idea of mimicry (1994) to examine the past relationship of dominant commercial productions and native nonprofit theatres. Although both Bhabha and Frenkel were discussing knowledge transfer, we use their conceptualizations to characterize and explore more deep...
The cross section for Bhabha scattering (e + e − → e + e −) with polarized electrons at the center of mass energy of the Z 0 resonance has been measured with the SLD experiment at the SLAC Linear Collider (SLC) during the 1992 and 1993 runs. The first measurement of the left-right asymmetry in Bhabha scattering (A e + e − LR (|cosθ|)) is presented. From A e + e − LR (|cosθ|) the effective weak ...
