Report

Iterative derivation of effective potentials to sample the conformational space of proteins at atomistic scale

Autor: Capelli, R., Paissoni, C., Sormanni, P., Tiana, G.

The current capacity of computers makes it possible to perform simulations of small systems with portable, explicit-solvent potentials achieving high degree of accuracy. However, simplified models must be employed to exploit the behaviour of large sy

The X-ray lightcurve of Sgr A* over the past 150 years inferred from Fe-Ka line reverberation in Galactic Centre molecular clouds

Autor: Capelli, R., Warwick, R. S., Porquet, D., Gillessen, S., Predehl, P.

We examine the temporal and spectral properties of nine Fe-Ka bright molecular clouds within about 30 pc of Sgr A*, in order to understand and constrain the primary energising source of the Fe fluorescence. Significant Fe-Ka variability was detected,

Fe Ka line emission from the Arches cluster region - evidence for ongoing particle bombardment?

Autor: Capelli, R., Warwick, R. S., Porquet, D., Gillessen, S., Predehl, P.

We present the results of eight years of XMM-Newton observations of the region surrounding the Arches cluster in the Galactic Center. We study the spatial distribution and temporal behaviour of the Fe-Ka line emission with the objective of identifyin

Report

Concurrent X-ray, near-infrared, sub-millimeter, and GeV gamma-ray observations of Sgr A*

Autor: Trap, G., Goldwurm, A., Dodds-Eden, K., Weiss, A., Terrier, R., Ponti, G., Gillessen, S., Genzel, R., Ferrando, P., Belanger, G., Clenet, Y., Rouan, D., Predehl, P., Capelli, R., Melia, F., Yusef-Zadeh, F.

The radiative counterpart of the supermassive black hole at the Galactic center (GC), Sgr A*, is subject to frequent flares visible simultaneously in X-rays and near-infrared (NIR). Often, enhanced radio variability from centimeter to sub-millimeter
