Constraining the Quenching Mechanisms in Galaxies

open access: yes, 2022
A number of theoretical mechanisms have been invoked to explain the transformation of star forming galaxies into quenched galaxies, such as the removal of gas by active galactic nuclei- (AGN) and star formation-driven galactic outflows, and the heating of the galaxy halo and subsequent halting of gas accretion caused by virial shocks and preventative ...

Shock metamorphic effects in Itokawa phosphates: A comparison with megaregolith‐derived meteorites

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 3, Page 351-370, March 2026.
Abstract Returned regolith samples from the asteroid Itokawa provide a unique opportunity to compare shock metamorphic effects in unconsolidated regolith materials with those preserved in lithified meteorites, that is, megaregolith. We analyzed four Itokawa particles (Ueda—RA‐QD02‐0519, Narahara—RA‐QD02‐0573, Domon—RA‐QD02‐0588, Ishiuchi—RX‐MD03‐0212 ...

Al‐Khadhaf: The first camera‐observed (H5–6) meteorite fall from Oman

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 3, Page 522-547, March 2026.
Abstract A fireball camera system installed in 2022 by the Oman Meteorite Monitoring Project (OMMP) as part of the Global Fireball Observatory (GFO) recorded a 3.2 s fireball on March 8, 2022 at 8:15 p.m. UTC. A meteoroid of 4 ± 2 kg entered the atmosphere at 14.0 km/s.

Evaluation of Zinc Borate and Melamine Polyphosphate Synergy on the Rheological, Thermal, Mechanical, Dimensional, and Flame Retardant Performance of rLLDPE/CaCO3 Composites for Pipes Applications

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 8, February 20, 2026.
A synergistic flame retardant containing melamine polyphosphate and zinc borate was prepared and applied to provide rLLDPE/CaCO3 composites with superior flame retardancy. ABSTRACT The use of recycled thermoplastics is crucial for addressing environmental challenges such as waste management and sustainability.

PAC. V. The Roles of Mass and Environment in the Quenching of Galaxies

open access: yesThe Astrophysical Journal
The roles that mass and environment play in galaxy quenching are still under debate. Leveraging the Photometric objects Around Cosmic webs method, we analyze the excess surface distribution ${\bar{n}}_{2}{w}_{{\rm{p}}}({r}_{{\rm{p}}})$ of photometric ...

Cluster induced quenching of galaxies in the massive cluster XMMXCSJ2215.9-1738 at z~1.5 traced by enhanced metallicities inside half R200

open access: yes, 2019
(Abridged) We explore the massive cluster XMMXCSJ2215.9-1738 at z~1.5 with KMOS spectroscopy of Halpha and [NII] covering a region that corresponds to about one virial radius.

Quenching time-scales of galaxies in the eagle simulations

open access: yesMonthly Notices of the Royal Astronomical Society, 2019
We use the \eagle\ simulations to study the connection between the quenching timescale, $ _{\rm Q}$, and the physical mechanisms that transform star-forming galaxies into passive galaxies. By quantifying $ _{\rm Q}$ in two complementary ways - as the time over which (i) galaxies traverse the green valley on the colour-mass diagram, or (ii) leave the ...
