Synoptic Sky Surveys and the Diffuse Supernova Neutrino Background: Removing Astrophysical Uncertainties and Revealing Invisible Supernovae

open access: yes, 2010
The cumulative (anti)neutrino production from all core-collapse supernovae within our cosmic horizon gives rise to the diffuse supernova neutrino background (DSNB), which is on the verge of detectability.

A window to the Galactic X-ray halo: The ISM towards the Lockman hole [PDF]

open access: yes, 2002
We present a combined X-ray/HI-analysis of the ISM towards the Lockman hole. This sky region is considered as the "window to the distant universe" because of its absolute lowest HI column density on the whole sky.

Deterministic Detection of Single Ion Implantation

open access: yesAdvanced Engineering Materials, Volume 28, Issue 11, 3 June 2026.
Focused ion beam implantation with high detection efficiencies will enable the rapid and scalable fabrication of advanced spin‐based technologies such as qubits. This work presents the detection efficiencies of a wide range of ions implanted into solid‐state hosts, with efficiencies of >90% recorded for ion species and substrate combinations of ...

The Hobby–Eberly Telescope VIRUS Parallel Survey (HETVIPS)

open access: yesThe Astrophysical Journal
The Hobby–Eberly Telescope (HET) VIRUS Parallel Survey (HETVIPS) is a blind spectroscopic program that sparsely covers approximately two-thirds of the celestial sphere and consists of roughly 252 million fiber spectra.

A Spherical Harmonic Analysis of Redshift Space [PDF]

open access: yes, 1994
We re-examine the effects of redshift space distortion in all-sky galaxy redshift surveys in the formalism of spherical harmonics. Within this framework we show how one can treat both the large-scale linear effects, and the small-scale nonlinear ...

NanoMOF‐Based Multilevel Anti‐Counterfeiting by a Combination of Visible and Invisible Photoluminescence and Conductivity

open access: yesAdvanced Functional Materials, Volume 36, Issue 43, 29 May 2026.
This study presents novel anti‐counterfeiting tags with multilevel security features that utilize additional disguise features. They combine luminescent nanosized Ln‐MOFs with conductive polymers to multifunctional mixed‐matrix membranes and powder composites. The materials exhibit visible/NIR emission and matrix‐based conductivity even as black bodies.

BELARUSIAN PROJECT “ASTROBLOKNOT” (ASTRONOMICAL NOTEBOOK) AND DATA MINING: RESULTS OBTAINED IN THE CONSTELLATION OF EQUULEUS

open access: yesOdessa Astronomical Publications, 2013
Many photometric sky surveys are currently available on the  open-access web-sources. The Northern Sky Variability Survey (NSVS), the All Sky Automated Survey 3 (ASAS-3) and the Catalina Real-Time Transient Survey (CRTS) are the most popular among them ...
