Kavli Affiliate: Edmund Bertschinger | Summary:Observations with the Rossi X-ray Timing Explorer (RXTE) have led to fundamental progress in the study of compact objects, in particular neutron stars and black holes. In this paper we present briefly some highlights from ~5 years of RXTE operations. | Search Query: arXiv Query: search_query=au:”Bradt Hale”&id_list=&start=0&max_results=10Read More
Kavli Affiliate: Edmund Bertschinger | Summary:A concept for an all-sky monitor mission substantially more powerful than the RXTE ASM is presented in brief. It makes use of 31 Gas Electron Multiplier (GEM) proportional counters to provide continuous monitoring of the entire x-ray sky, except for earth occultations and a small region around the sun. This […]
Kavli Affiliate: Stavros Katsanevas | Summary:We reanalyze the results of the chargino searches at LEP (on the basis of the DELPHI 189 GeV data sample), including the possibility of complex MSSM parameters. We point out the possible differences between the complex- and real-parameter analysis. We check that the regions excluded by “standard” analyses remain generally […]
Kavli Affiliate: Edmund Bertschinger | Summary:Using data from the All-Sky Monitor aboard the Rossi X-ray Timing Explorer (RXTE), we found that the 1.5-12 keV X-ray count rate of Cyg X-1 is, on time scales from 90 seconds to at least 10 days, strongly correlated with the spectral hardness of the source in the soft state, […]
Kavli Affiliate: Edmund Bertschinger | Summary:We present a tabulation of 46 transient x-ray sources monitored with the All-Sky Monitor (ASM) on the Rossi X-ray Timing Explorer (RXTE). They fall into four broad categories: short (~d), intermediate, and long (>500 d) duration of outbursts, and long period binary systems that flare up at periastron (e.g., Be […]
Kavli Affiliate: Edmund Bertschinger | Summary:We present light curves of a sample of "transient" sources observed with the All-Sky Monitor (ASM) of the Rossi X-ray Timing Explorer (RXTE). The light curves extend over 3.5 years. They are presented in three groups: six neutron-star systems, eight black-hole-candidate systems, and an additional diverse set of six objects […]
Kavli Affiliate: Edmund Bertschinger | Summary:X 1908+075 is an optically unidentified and highly absorbed X-ray source that appears in early surveys such as Uhuru, OSO-7, Ariel V, HEAO-1, and the EXOSAT Galactic Plane Survey. These surveys measured a source intensity in the range of 2-12 mCrab at 2-10 keV, and the position was localized to […]
Kavli Affiliate: Kunio Inoue | Summary:A search for day-night variations in the solar neutrino flux resulting from neutrino oscillations has been carried out using the 504 day sample of solar neutrino data obtained at Super-Kamiokande. The absence of a significant day-night variation has set an absolute flux independent exclusion region in the two neutrino oscillation […]
Kavli Affiliate: Richard Partridge | Summary:This paper summarizes a variety of recent results on heavy quark production and decay. Considerable progress has been made by CDF and D0 in measuring top quark production and decay properties. The top quark mass been measured with an uncertainty that is less than 3%, a relative precision that is […]
Kavli Affiliate: Yukari Ito | Summary:Let $G$ be a nontrivial finite subgroup of $SL_n(C)$. Suppose that the quotient singularity $C^n/G$ has a crepant resolution $Ď€colon Xto C^n/G$ (i.e. $K_X = shfO_X$). There is a slightly imprecise conjecture, called the McKay correspondence, stating that there is a relation between the Grothendieck group (or (co)homology group) of […]
