A giant ring-like structure at 0.78
According to the cosmological principle, Universal large-scale structure is homogeneous and isotropic. The observable Universe, however, shows complex structures even on very large scales. The recentExpand
Searching for differences in Swift's intermediate GRBs
Context. Gamma-ray bursts are usually classified in terms their high-energy emission into either short-duration or long-duration bursts, which presumably reflect two different types of progenitors.Expand
Impact on cosmology of the celestial anisotropy of the short gamma-ray bursts
Recently the anisotropy of the short gamma-ray bursts detected by BATSE was announced (Vavrek et al. 2008). The impact of this discovery on cosmology is discussed. It is shown that the anisotropyExpand
The AKARI Far-Infrared Surveyor young stellar object catalog
We demonstrate the use of the AKARI all-sky survey photometric data in the study of galactic star formation. Our aim was to select young stellar objects (YSOs) in the AKARI Far-Infrared SurveyorExpand
On the origin of the dark gamma-ray bursts
The origin of dark bursts—i.e. that have no observed afterglows in X-ray, optical/NIR and radio ranges—is unclear yet. Different possibilities—instrumental biases, very high redshifts, extinction inExpand
Estimation of the Redshifts for Long Gamma‐Ray Bursts
It is known that the soft tail of gamma‐ray bursts’ spectra show excesses from the exact power‐law dependence. In this article we show that this departure can be detected in the peak flux ratios ofExpand
Spectral classification and variation of Fermi GRBs
The Fermi GBM catalog contains general physical quantities of the observed objects and also estimated parameters (peak energy, spectral indices, intensity) from four fitted spectral models (Band,Expand
The THESEUS space mission concept: science case, design and expected performances
Abstract THESEUS is a space mission concept aimed at exploiting Gamma-Ray Bursts for investigating the early Universe and at providing a substantial advancement of multi-messenger and time-domainExpand
Classifying GRB 170817A/GW170817 in a Fermi duration–hardness plane
GRB 170817A, associated with the LIGO-Virgo GW170817 neutron-star merger event, lacks the short duration and hard spectrum of a Short gamma-ray burst (GRB) expected from long-standing classificationExpand
