The Collimation and Energetics of the Brightest Swift Gamma-Ray Bursts
S. B. Cenko,Dale A. Frail,Fiona A. Harrison,Shrinivas R. Kulkarni,Ehud Nakar,Poonam Chandra,Nat Butler,D. B. Fox,Avishay Gal-Yam,M. M. Kasliwal,János Kelemen,Dae-Sik Moon,P. A. Price,A. Rau,Alicia M. Soderberg,Harry I. Teplitz,Michael W. Werner,Douglas C.-J. Bock,J. S. Bloom,D. Starr,Alexei V. Filippenko,Roger A. Chevalier,N. Gehrels,J. N. Nousek,Tsvi Piran +24 more
TL;DR: In this article, the authors present multi-wavelength (radio through X-ray) observations of GRBs 050820A, 060418, and 080319B, and construct afterglow models to extract the opening angle and beaming-corrected energy release for all three events.

TL;DR: In this article, the authors present multicolor optical observations of long-duration γ-ray bursts (GRBs) made over a three-year period with the robotic Palomar 60 inch telescope (P60).
Journal ArticleDOI
The outburst and nature of two young eruptive stars in the North America/Pelican Nebula Complex
Ágnes Kóspál,P. Ábrahám,J. A. Acosta-Pulido,J. A. Acosta-Pulido,M. J. Arévalo Morales,M. J. Arévalo Morales,M. I. Carnerero,M. I. Carnerero,E. Elek,János Kelemen,Mária Kun,András Pál,András Pál,Róbert Szakáts,Krisztián Vida +14 more
TL;DR: In this article, the authors analyzed the spectral energy distributions of two young stellar objects, HBC 722 and VSX J205126.1+440523, in order to determine the true nature of these two objects.
Journal ArticleDOI
Over-expression of dopamine D2 receptor and inwardly rectifying potassium channel genes in drug-naive schizophrenic peripheral blood lymphocytes as potential diagnostic markers.
Ágnes Zvara,G. Szekeres,Zoltán Janka,János Kelemen,Csongor Cimmer,Miklós Sántha,László G. Puskás +6 more
TL;DR: Increased mRNA levels were confirmed by quantitative real-time PCR (QRT-PCR) using the SybrGreen method and dual labeled TaqMan probes and the use of both molecular markers allows a more rapid and precise prediction of schizophrenia and might help find the optimal medication for schizophrenic patients.
