The Bochum Survey of the Southern Galactic Disk: III. Complete Data Release

open access: yesAstronomische Nachrichten, Volume 347, Issue 3, March 2026.
ABSTRACT The Southern Galactic Disk Survey (GDS) monitored a mosaic of 268 fields along a 6°$$ {6}^{{}^{\circ}} $$‐wide stripe in the southern Galactic disk with simultaneous observations in r′$$ {r}^{\prime } $$ and i′$$ {i}^{\prime } $$ (7m≲r′,i′≲18m$$ {7}^{\mathrm{m}}\lesssim {r}^{\prime },{i}^{\prime}\lesssim {18}^{\mathrm{m}} $$) from September ...

«Différant des Autres», Espacements et Temporalités Spectrales

open access: yesAnthropology of Consciousness, Volume 37, Issue 1, Spring 2026.
ABSTRACT That night that he agreed to our suggestion that we accompany him outside, for the whole night or until the overflow has passed, M seemed to be in direct contact with all the layers of astronomy, inhabiting all temporalities simultaneously. Outside, lying/sitting on the picnic table, in the pitch‐black darkness of the night in the woods, under

Cherenkov Telescope Array Observatory: Die Zukunft der Gammaastronomie

open access: yesPhysik in unserer Zeit, Volume 57, Issue 1, Page 10-18, January 2026.
Im Jahr 1989 hat das Wipple‐Observatorium die erste Quelle hochenergetischer Gammastrahlung entdeckt. 2002 waren dann sechs Quellen bekannt, 2024 schon mehr als 300. Und das ist immer noch lediglich die Spitze des Eisbergs in der jungen Geschichte der Gammaastronomie.

Deterministic Nanofabrication of Quantum Dot ‐ Circular Bragg Grating Resonators with High Process Yield Using In Situ Electron Beam Lithography

open access: yesAdvanced Quantum Technologies, Volume 9, Issue 1, January 2026.
We demonstrate that deterministic in situ electron‐beam lithography enables precise integration of single quantum dots into compact circular Bragg grating resonators, achieving high extraction efficiency with only 3–4 rings. Across 95 devices, the approach delivers >$>$90% alignment yield and bright, narrow‐linewidth single‐photon emission, providing a
