THE MASS DEPENDENCE OF DWARF SATELLITE GALAXY QUENCHING [PDF]
The Astrophysical Journal, 2014 We combine observations of the Local Group with data from the NASA-Sloan Atlas to show the variation in the quenched fraction of satellite galaxies from low mass dwarf spheroidals and dwarf irregulars to more massive dwarfs similar to the Magellanic clouds.

Inside-out versus Outside-in Quenching of MaNGA Galaxies: Dependence on Stellar Mass and Environment
The Astrophysical JournalGalaxy quenching, the cessation of star formation, can proceed in spatially distinct ways, commonly described as inside-out or outside-in. However, the inferred quenching pattern depends strongly on how quenched or quenching regions are defined ...

Health Science Reports, Volume 9, Issue 8, August 2026.ABSTRACT Background and Aims Bovine anaplasmosis is an intracellular tick‐borne, non‐contagious disease caused by gram‐negative bacteria of the family Anaplasmataceae and order Rickettsia. Anaplasma phagocytophilum is the etiological agent for human granulocytic anaplasmosis associated with severe health implications in parts of Europe and the USA and ...

Constraining the Quenching Mechanisms in Galaxies
, 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 ...

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.Abstract The Cassini spacecraft spent 13 years orbiting Saturn, quasi‐continuously measuring Saturn's radio emissions. One of the key elements of the radio spectrum at Saturn is the Saturn Kilometric Radiation (SKR), and several studies have been written on events called Low Frequency Extensions (LFEs) which represent strong, continuous extensions of ...

Nanoscale space weathering features in mature lunar soil revealed by TEM and APT
Meteoritics &Planetary Science, Volume 61, Issue 8, Page 2048-2072, August 2026.Abstract Space weathering significantly alters the optical, chemical, and structural properties of lunar regolith at micro‐ and nanoscales; yet detailed nanoscale variability within individual soils remains underexplored. Here we apply transmission electron microscopy (TEM) and atom probe tomography to four mineral grains (olivine, ilmenite, and two ...

The Astrophysical Journal, 2023 How the environment influences the most massive galaxies is still unclear. To explore the effects of the environment on morphology and star formation in the most massive galaxies at high redshift, we select galaxies with stellar mass $\mathrm{log}({M}_ ...

Enantioselective Separation and Negative Transport of Chiral Particles via Optical Needle Fields
Nanophotonics, Volume 15, Issue 13, 13 July 2026.This work proposes an all‐optical strategy that leverages a tailored optical needle field for the enantioselective separation and 3D manipulation of chiral particles. By introducing phase modulation, we engineer a dual‐needle configuration capable of spatially separating and negatively transporting both enantiomers within a single system, offering a ...
