QPEs from EMRI Debris Streams Impacting Accretion Disks in Galactic Nuclei
The Astrophysical JournalQuasi-periodic eruption (QPE) sources in galactic nuclei are often associated with a stellar object orbiting a supermassive black hole with an hours to days period, which is brought in as an extreme mass-ratio inspiral (EMRI).

Advanced Materials, EarlyView.Gold‐stabilized copper suppresses hydroxide‐driven deactivation during anodic hydrogen evolution from furfural. Pairing this low‐potential anode with CO‐to‐ethylene electroreduction enables sub‐1 V operation at 400 mA cm−2, high single‐pass CO conversion, and co‐production of ethylene, furoic acid, and a separate hydrogen stream.

Stellar Streams Reveal the Mass Loss of Globular Clusters
The Astrophysical Journal LettersGlobular cluster (GC) streams, debris of stars tidally stripped from their progenitor GCs, have densities that correlate positively with the GC mass-loss rate.

Improved Particle Spray Algorithm for Modeling Globular Cluster Streams
The Astrophysical Journal Supplement SeriesStellar streams that emerge from globular clusters (GCs) are thin stellar structures spread along the orbits of progenitor clusters. Numerical modeling of these streams is essential for understanding their interaction with the host galaxy's mass ...

Advanced Materials, EarlyView.A circular upcycling strategy transforms waste poly(ethylene terephthalate) bottles into microwave‐responsive Ni@C catalyst featuring lattice‐distorted nickel cores and defective carbon shells. These strain‐rich heterointerfaces enhance dielectric loss and promote localized microwave hotspots, accelerating peroxymonosulfate activation and polymer‐chain

Dynamical streams in the local stellar halo
Monthly Notices of the Royal Astronomical SocietyABSTRACT Co-moving groups of stars (streams) are well known in the velocity space of the disc near the Sun. Many are thought to arise from resonances with the Galactic bar or spiral arms. In this work, we search for similar moving groups in the velocity space of the halo, at low angular momentum. From the asymmetry of the radial velocity

The Kinematically Hot, Extremely Metal-poor C-19 Stellar Stream in DESI DR2
The Astrophysical JournalStellar streams are the result of a host galaxy’s gravitational potential tidally disrupting satellite dwarf galaxies and globular clusters (GCs), causing them to grow leading and trailing tidal tails.
