Optimal filter systems for photometric redshift estimation
N. Benitez, M. Moles, J. A. L. Aguerri +18
In the next years, several cosmological surveys will rely on imaging data to estimate the redshift of galaxies, using traditional filter systems with 4-5 optical broad bands; narro…
Photometry and Spin Rate Distribution of Small-Sized Main Belt Asteroids
D. Polishook, N. Brosch
Photometry results of 32 asteroids are reported from only seven observing nights on only seven fields, consisting of 34.11 cumulative hours of observations. The data were obtained…
Linear dynamics of weakly viscous accretion disks: A disk analog of Tollmien-Schlichting waves
O. M. Umurhan, G. Shaviv
This paper discusses new perspectives and approaches to the problem of disk dynamics where, in this study, we focus on the effects of viscous instabilities influenced by boundary e…
On Dark Energy and Dark Matter (Part II)
Shlomo Barak, Elia M. Leibowitz
Phenomena currently attributed to Dark Matter (DM) and Dark Energy (DE) are merely a result of the interplay between gravitational energy density, caused by the contraction of spac…
Transiting exoplanets from the CoRoT space mission VI. CoRoT-Exo-3b: The first secure inhabitant of the brown-dwarf desert
M. Deleuil, H. J. Deeg, R. Alonso +2
Context. The CoRoT space mission routinely provides high-precision photometric measurements of thousands of stars that have been continuously observed for months. Aims. The discove…
Recollimation and Radiative Focusing of Relativistic Jets: Applications to Blazars and M87
Omer Bromberg, Amir Levinson
Recent observations of M87 and some blazars reveal violent activity in small regions located at relatively large distances from the central engine. Motivated by these consideration…
