Fortschritte der Physik, Volume 74, Issue 4, April 2026.Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.

Ultraluminous X-ray sources as super-Eddington accretion disks [PDF]
, 2018 Copyright © 2018 by the Editors.All rights reserved. The origin of Ultraluminous X-ray sources (ULXs) in external galaxies whose X-ray luminosities exceed those of the brightest black holes in our Galaxy by hundreds and thousands of times is mysterious ...

Balance among gravitational instability, star formation and accretion determines the structure and evolution of disc galaxies [PDF]
, 2013 Over the past 10 Gyr, star-forming galaxies have changed dramatically, from clumpy and gas rich, to rather quiescent stellar-dominated disks with specific star formation rates lower by factors of a few tens. We present a general theoretical model for how

Discovering the Mass-Scaled Damping Timescale from Microquasars to Blazars
The Astrophysical Journal LettersStudying the variability of the accretion disks of black holes and jets is important to identify their internal physical processes. In this Letter, we obtain the characteristic damping timescale of 34 blazars and 7 microquasars from the Fermi-Large Area ...

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.Abstract Xenon (Xe) is a heavy noble gas with intriguing chemical properties, such as having several stable isotopes and the ability to form compounds under extreme conditions. Despite the predictions based on cosmochemical models that suggest xenon should be relatively abundant in planetary reservoirs, empirical data indicate a significant depletion ...

Strongly star-forming rotating disks in a complex merging system at z = 4,7 as revealed by ALMA [PDF]
, 2013 We performed a kinematical analysis of the [CII] line emission of the BR 1202-0725 system at z~4,7 using ALMA observations. The most prominent sources of this system are a quasar and a submillimeter galaxy, separated by a projected distance of about 24 ...

The Astrophysical JournalGamma-ray bursts (GRBs), both from the merger of binary compact objects (short GRBs) and the collapse of massive stars (long GRBs), are expected to occur in dense environments, e.g., the accretion disks of active galactic nuclei (AGNs).

SwarmGenomics: A Unified Pipeline for Individual‐Based Whole‐Genome Analyses
Molecular Ecology Resources, Volume 26, Issue 3, April 2026.ABSTRACT Advances in sequencing technologies have made whole‐genome data widely accessible, enabling research in population genetics, evolutionary biology, and conservation. However, analysing whole‐genome sequencing (WGS) data remains challenging, often requiring multiple specialised tools and substantial bioinformatics expertise.

Jet formation in BL Lacertae objects with different accretion modes
, 2003 We estimate the masses of massive black holes in BL Lac objects from their host galaxy luminosity. The power of jets and central optical ionizing luminosity for a sample of BL Lac objects are derived from their extended radio emission and the narrow-line

Programming Next‐Generation Synthetic Biosensors by Genetic Circuit Design
Advanced Science, Volume 13, Issue 14, 9 March 2026.Synthetic biology enables genetic circuit‐based biosensing to detect diverse targets, process signals, and transduce them into readable outputs or intracellular regulatory activities. However, field deployment and real‐world application of such synthetic biosensors face considerable challenges in sensitivity, specificity, speed, stability, and ...
