Optical Monitoring of PKS 2155-304 during August-September 2004 with the KVA telescope
S. Ciprini, E. Lindfors, K. Nilsson +1
The southern gamma-ray blazar PKS 2155-304 is one of the brightest and most intensively studied prototypes of BL Lac object. PKS 2155-304 has recently aroused the interest of Chere…
Uniform Bound for Hecke L-Functions
Matti Jutila, Yoichi Motohashi
Our principal aim in the present article is to establish a uniform hybrid bound for individual values on the critical line of Hecke -functions associated with cusp forms over th…
An extremely curved relativistic jet in PKS 2136+141
T. Savolainen, K. Wiik, E. Valtaoja +1
We report the discovery of an extremely curved jet in the high frequency peaking GPS quasar PKS 2136+141. Our multi-frequency VLBA images show a bending jet making a turn-around of…
Multifrequency Observations of the Gamma-Ray Blazar 3C 279 in Low-State during Integral AO-1
W. Collmar, M. Böttcher, V. Burwitz +19
We report first results of a multifrequency campaign from radio to hard X-ray energies of the prominent gamma-ray blazar 3C 279 during the first year of the INTEGRAL mission. The v…
Improved efficiency of stimulated Raman adiabatic passage in photoassociation of a Bose-Einstein condensate
Matt Mackie, Kari Harkonen, Anssi Collin +2
We theoretically examine Raman photoassociation of a Bose-Einstein condensate, revisiting stimulated Raman adiabatic passage (STIRAP). Due to collisional mean-field shifts, efficie…
Periodicity and Unbordered Words: A Proof of the Extended Duval Conjecture
Tero Harju, Dirk Nowotka
The relationship between the length of a word and the maximum length of its unbordered factors is investigated in this paper. Consider a finite word w of length n. We call a word b…
