The numbers behind Plimpton 322 [PDF]

open access: yesarXiv, 2011
A mathematically and culturally natural modification of Evart Bruins' explanation of the genesis of the numbers on the Old Babylonian tablet Plimpton 322 gives an economical accounting for the "missing pairs" in his reconstruction. When the new scheme is used to predict the numbers that would follow those on Plimpton 322, the results add five new rows ...

A failed outburst of H1743−322 [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2009
We report on a campaign of X-ray and soft gamma-ray observations of the black hole candidate H 1743-322 (also named IGR J17464-3213), performed with the RXTE, INTEGRAL and Swift satellites. The source was observed during a short outburst between 2008 October 03 and 2008 November 16.

Anomalous outbursts of H 1743-322 [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2019
Abstract Using soft (1.5–3 keV) and hard (3–12 keV) photon counts of All Sky Monitor (ASM) in Rossi X-ray Timing Explorer (RXTE) satellite, we have proposed recently that there is a significant time lag between the infall time-scales of two components in the Two-Component Advective Flow paradigm, where a standard slow moving Keplerian ...

Plimpton 322: A Study of Rectangles [PDF]

open access: yesFoundations of Science, 2021
AbstractPlimpton 322 is one of the most sophisticated and interesting mathematical objects from antiquity. It is often regarded as teacher’s list of school problems, however new analysis suggests that it relates to a particular geometric problem in contemporary surveying.

Discovery of X-ray Jets in the Microquasar H 1743-322 [PDF]

open access: yesAstrophys.J.632:504-513,2005, 2005
We report on the formation and evolution of two large-scale, synchrotron-emitting jets from the black hole candidate H 1743-322 following its reactivation in 2003. In November 2003 after the end of its 2003 outburst, we noticed, in observations with the Australia Telescope Compact Array, the presence of a new and variable radio source about 4.6" to the

INTEGRAL observations of the black hole candidate H 1743-322 in outburst [PDF]

open access: yesAstron.Astrophys.411:L421-L426,2003, 2003
INTEGRAL made 3 observations in 2003 April of the black hole candidate H 1743-322 during the rising part, and close to the maximum, of an outburst. H 1743-322 was previously observed in outburst in 1977-1978. The source is located in a crowded region of the sky (l = 357 deg, b = -2 deg) and at least 18 sources are clearly detected in the field of view ...

Heat expansion of star-like cosmic objects induced by the cosmological expansion [PDF]

open access: yesAstron. Nachr. 322 (2001) 207-210, 2002
The heat expansion of a star-like cosmic object, induced by the cosmological bremsheat production within a moving body, that was predicted by the Projective Unified field Theoriy of the author, is approximately treated. The difference to planet-like bodies investigated previously arises from another material constitution. The exponential-like expansion

Operator ordering for generally covariant systems [PDF]

open access: yesNucl.Phys.Proc.Suppl. 88 (2000) 322-325, 2000
The constraint operators belonging to a generally covariant system are found out within the framework of the BRST formalism. The result embraces quadratic Hamiltonian constraints whose potential can be factorized as a never null function times a gauge invariant function.
