Chandra Observations of Gas Stripping in the Elliptical Galaxy NGC 4552 in the Virgo Cluster [PDF]
, 2005 We use a 54.4 ks Chandra observation to study ram pressure stripping in NGC 4552 (M89), an elliptical galaxy in the Virgo Cluster. Chandra images in the 0.5-2 keV band show a sharp leading edge in the surface brightness 3.1 kpc north of the galaxy center,

New Arabic Records From Cairo on Supernovae 1181 and 1006
Astronomische Nachrichten, EarlyView.ABSTRACT The remnant of the historical supernova SN 1181 is under discussion: While the previously suggested G130.7+3.1 (3C58) appears too old (3000–5000 year), the unusual star IRAS00500+6713 with a surrounding nebula (Pa‐30) has an expansion age not inconsistent with a SN Iax explosion in ad 1181 under the assumption that neither acceleration nor ...

Lopsidedness of cluster galaxies in modified gravity
, 2010 We point out an interesting theoretical prediction for elliptical galaxies residing inside galaxy clusters in the framework of modified Newtonian dynamics (MOND), that could be used to test this paradigm.

Alignment and morphology of elliptical galaxies: the influence of the cluster tidal field
, 1994 We investigate two possible effects of the tidal field induced by a spherical cluster on its elliptical galaxy members: the modification of the ellipticity of a spherical galaxy and the isophotal alignment in the cluster radial direction of a misaligned ...

Triaxiality in elliptical galaxies
Monthly Notices of the Royal Astronomical Society, 1980 A simple geometrical model of elliptical galaxies having shells with different axial ratios c/a, b/a has been produced to interpret three fundamental key-features of elliptical galaxies: (1) the distribution of the maximum flattening observed; (2) the percentage of ellipticals showing twisting; and (3) the correlation between maximum twisting and ...

Geometrical evidence for dark matter: X-ray constraints on the mass of the elliptical galaxy NGC 720 [PDF]
, 1993 We describe (1) a new test for dark matter and alternate theories of gravitation based on the relative geometries of the X-ray and optical surface brightness distributions and an assumed form for the potential, of the optical light, (2) a technique to ...

Food Frontiers, EarlyView.Transcriptomics revealed the metabolism of Lactiplantibacillus plantarum during soy milk fermentation. The fermentation of soy milk released aroma compounds and health‐beneficial metabolites. ABSTRACT The fermentation of plant‐based beverages, such as organic and locally produced soy juice (SJ), offers a sustainable way to develop dairy alternatives ...

Two-component mass models of the lensing galaxy in the quadruply imaged supernova iPTF16geu
The Open Journal of Astrophysics, 2020 The first resolved, multiply imaged supernova Type Ia, iPTF16geu, was observed 4 years ago, five decades after such systems were first envisioned. Because of the unique properties of the source, these systems hold a lot of promise for the study of galaxy

The Carnegie-Irvine Galaxy Survey. X. Bulges in Stellar Mass–based Scaling Relations
The Astrophysical Journal Supplement Series, 2022 We measure optical colors for the bulges of 312 disk galaxies from the Carnegie-Irvine Galaxy Survey and convert their previously available R -band structural parameters to stellar-mass parameters.
