Caught in the Act: Detections of Recoiling Supermassive Black Holes from Simulations

The Astrophysical Journal
We study the detectability of supermassive black holes (SMBHs) with masses of M _•  ≳ 10 ^9 M _⊙ displaced by gravitational wave recoil kicks ( v _kick  = 0–2000 km s ^−1 ) in simulations of merging massive ( M _⋆  > 10 ^11 M _⊙ ) early-type galaxies ...

Nullwertige Nickelatome stabilisiert in oberflächengestützten metallorganischen Ketten

Angewandte Chemie, EarlyView.
Mit 9,10‐Dicyanoanthracen koordinierte nullwertige Ni(0) d10‐Zentren auf Ag(100), die eine metallorganische Kette mit quasi‐eindimensionaler Metall‐Ligand‐Wechselwirkung bilden. ZUSAMMENFASSUNG Die Stabilisierung von nullwertigen Ni(0)‐Zentren in ausgedehnten Koordinationsnetzwerken bleibt aufgrund ihrer ausgeprägten Reaktivität und Anfälligkeit für ...

Calibrating Galaxy Infall Times in Groups and Clusters with IllustrisTNG Simulations

The Astrophysical Journal
The time since a galaxy first became a satellite is central to understanding how environment drives galaxy evolution, yet it cannot be measured directly.

Zero‐Valent Nickel Stabilized in Surface‐Supported Metal–Organic Chains

Angewandte Chemie International Edition, EarlyView.
9,10‐Dicyanoanthracene coordinates Ni atoms on Ag(100) to form metal–organic chains that stabilize zero‐valent Ni(0) (d10) centers with quasi‐one‐dimensional metal–ligand electronic coupling. ABSTRACT The stabilization of zero‐valent nickel Ni(0) centers in extended coordination networks remains a major challenge due to their pronounced reactivity and ...

Tracing the evolutionary history of the morpho‐anatomy of baculum in primates

The Anatomical Record, EarlyView.
Abstract Animal morphology reflects both evolutionary history and present‐day adaptation. Male mammal copulatory structures such as the baculum (penile bone) are ideal for studying these processes because of their complexity and high interspecific variability. In primates, however, research has focused mostly on baculum length.

The THESEUS Space Mission and the Infrared Telescope Calibration Unit

Astronomische Nachrichten, EarlyView.
ABSTRACT The Transient High‐Energy Sky and Early Universe Surveyor (THESEUS) is an ESA M7 mission concept currently in Phase A, designed to exploit gamma‐ray bursts to probe the early Universe while advancing multi‐messenger and time‐domain astrophysics. To achieve its ambitious goals, THESEUS will combine wide‐band x‐ray and gamma‐ray monitors with an

The ORCA‐TWIN qCMOS Experiment I. Science Case and Commissioning at Calar Alto Observatory

Astronomische Nachrichten, EarlyView.
ABSTRACT We describe a pilot study to explore a new generation of fast and low noise CMOS image sensors for time domain astronomy, using two remote telescopes with a baseline of 1635 km. The experiment involves direct imaging with novel qCMOS image sensor technology that combines fast readout with sub‐electron readout noise.

Targeting Amastigote and Trypomastigote Phases: Multi‐Epitope Vaccine Strategy Against Trypanosoma cruzi

Biotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Effective vaccines against Trypanosoma cruzi, the causative agent of Chagas disease, are urgently needed. Here, we report the design and in silico validation of a novel multiepitope vaccine construct targeting the key surface proteins ASP‐2 and gp82. Using a comprehensive immunoinformatics pipeline, we identified and selected 38 potent T‐cell (
