A long hard look at MCG–6-30-15 with XMM-Newton
- A. Fabian, S. Vaughan, U. Maryland
- Physics
- 6 June 2002
We present the first results from a 325-ks observation of the Seyfert 1 galaxy MCG–6-30-15 with XMM-Newton and BeppoSAX. The strong, broad, skewed iron line is clearly detected and is well…
The evolution of the timing properties of the black-hole transient GX 339-4 during its 2002/2003 outburst
- T. Belloni, J. Homan, S. Utrecht
- Physics
- 26 April 2005
We present the results of the timing and color analysis of more than two hundred RXTE/PCA observations of the bright black-hole transient GX 339-4 obtained during its 2002/2003 outburst. The…
Fast-evolving weather for the coolest of our two new substellar neighbours
- M. Gillon, A. Triaud, Switzerland.
- Physics, Geology
- 1 April 2013
We present the results of intense photometric monitoring in the near-infrared ( 0.9 m) with the TRAPPIST robotic telescope of the newly discovered binary brown dwarf WISE J104915.57-531906.1, the…
Long term variability of Cygnus X-1. I. X-ray spectral-temporal correlations in the hard state
- K. Pottschmidt, J. Wilms, Ucb
- Physics
- 13 February 2002
We present the long term evolution of the timing properties of the black hole candidate Cygnus X-1 in the 0.002-128 Hz frequency range as monitored from 1998 to 2001 with the Rossi X-ray Timing…
NONLINEAR QUANTUM MECHANICS IMPLIES POLYNOMIAL-TIME SOLUTION FOR NP-COMPLETE AND P PROBLEMS
- D. Abrams, S. L. D. O. Physics, Mit, Dept. of Communications Engineering
- Physics, Computer Science
- 21 January 1998
This work provides algorithms that solve NP-complete and #P oracle problems by exploiting nonlinear quantum logic gates, and it is argued that virtually any deterministic non linear quantum theory will include such gates.
First results from the IllustrisTNG simulations: matter and galaxy clustering
- V. Springel, R. Pakmor, C. University
- Physics
- 11 July 2017
Hydrodynamical simulations of galaxy formation have now reached sufficient volume to make precision predictions for clustering on cosmologically relevant scales. Here we use our new IllustrisTNG…
The Illustris simulation: the evolving population of black holes across cosmic time
- D. Sijacki, M. Vogelsberger, Stsci
- Physics
- 28 August 2014
We study the properties of black holes and their host galaxies across cosmic time in the Illustris simulation. Illustris is a large-scale cosmological hydrodynamical simulation which resolves a…
The 'Quiescent' black hole in M87
- C. Reynolds, T. D. Matteo, Usa
- Physics
- 14 October 1996
It is believed that most giant elliptical galaxies possess nuclear black holes with masses in excess of 10 8 M⊙. Bondi accretion from the interstellar medium might then be expected to produce…
X-Ray Emission From the Shell-Type SNR G347.3-0.5
- P. Slane, B. Gaensler, R. University
- Physics
- 23 June 1999
Recent ASCA observations of G347.3 - 0.5, an SNR discovered in the ROSAT All-Sky Survey, reveal nonthermal emission from a region along the northwestern shell (Koyama et al. 1997). Here we report on…
ETHOS—an effective theory of structure formation: From dark particle physics to the matter distribution of the Universe
- F. Cyr-Racine, K. Sigurdson, Hits
- Physics
- 16 December 2015
We formulate an effective theory of structure formation (ETHOS) that enables cosmological structure formation to be computed in almost any microphysical model of dark matter physics. This framework…
