Dynamical and evolutionary constraints on the nature and origin of hypervelocity stars
Hagai B. Perets
In recent years several hypervelocity stars (HVSs) have been observed in the halo of our Galaxy. Such stars are thought to be ejected through dynamical interactions near the massiv…
Getting a kick out of the stellar disk(s) in the galactic center
Hagai B. Perets, Gabor Kupi, Tal Alexander
Recent observations of the Galactic center revealed a nuclear disk of young OB stars, in addition to many similar outlying stars with higher eccentricities and/or high inclinations…
Temperature fluctuations of interstellar dust grains
Kobi Horn, Hagai B. Perets, Ofer Biham
The temperatures of interstellar dust grains are analyzed using stochastic simulations, taking into account the grain composition and size and the discreteness of the photon flux.…
Formation of molecular hydrogen on amorphous silicate surfaces
Ling Li, Giulio Manico, Emanuele Congiu +8
Experimental results on the formation of molecular hydrogen on amorphous silicate surfaces are presented and analyzed using a rate equation model. The energy barriers for the relev…
Molecular Hydrogen Formation on Low Temperature Surfaces in Temperature Programmed Desorption Experiments
G. Vidali, V. Pirronello, L. Li +7
The study of the formation of molecular hydrogen on low temperature surfaces is of interest both because it allows to explore elementary steps in the heterogeneous catalysis of a s…
Realization of quantum walks with negligible decoherence in waveguide lattices
Hagai B. Perets, Yoav Lahini, Francesca Pozzi +3
Quantum random walks are the quantum counterpart of classical random walks, and were recently studied in the context of quantum computation. A quantum random walker is subject to s…
Massive perturbers and the efficient merger of binary massive black holes
Hagai B. Perets, Tal Alexander
We show that dynamical relaxation in the aftermath of a galactic merger and the ensuing formation and decay of a binary massive black hole (MBH), are dominated by massive perturber…
Molecular Hydrogen Formation on Amorphous Silicates Under Interstellar Conditions
Hagai B. Perets, Adina Lederhendler, Ofer Biham +8
Experimental results on the formation of molecular hydrogen on amorphous silicate surfaces are presented for the first time and analyzed using a rate equation model. The energy bar…
Deterministic and Stochastic Simulations of Simple Genetic Circuits
Ofer Biham, Nathalie Q. Balaban, Adiel Loinger +2
We analyze three simple genetic circuits which involve transcriptional regulation and feedback: the autorepressor, the switch and the repressilator, that consist of one, two and th…
