The habitability of large elliptical galaxies [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2020
ABSTRACT Based on numbers of stars, supernova rates, and metallicity, a prior study concluded that large elliptical galaxies contain up to 10 000 times more habitable planets than the Milky Way and are thus the ‘cradles of life’. Using the results of their model and taking into account galactic number distributions and supernova rates, I

Hot interstellar matter in elliptical galaxies [PDF]

open access: yes, 2009
Based on a number of new discoveries resulting from 10 years of Chandra and XMM-Newton observations and corresponding theoretical works, this is the first book to address significant progress in the research of the Hot Interstellar Matter in Elliptical ...

Equilibrium Figures inside the Dark-Matter Ring and the Shapes of Elliptical Galaxies

open access: yesOpen Astronomy, 2015
We solve the general problem of the theory of equilibrium figures and analyze two classes of liquid rotating gravitating figures residing inside a gravitating ring or torus.

Galaxy Merging and the Fundamental Plane of Elliptical Galaxies [PDF]

open access: yes, 2006
We present preliminary results of numerical simulations of dissipationless merging of stellar systems, aimed at exploring the consequences of merging between gas free, spheroidal systems. In particular, we study the dynamical and structural characteristics of hierarchical merging between equal mass stellar systems, and we compare the properties of the ...

Gravitational Lensing by Elliptical Galaxies [PDF]

open access: yesSymposium - International Astronomical Union, 2005
The probability that high-redshift quasars are gravitationally-lensed by intervening galaxies increases rapidly with the cosmological constant, ΩΛ0 (whilst being only weakly dependent on the density parameter, Ωm0), and the low number of lenses observed implies that ΩΛ0 ≲ 0.7 (e.g. Kochanek 1996).

Resolving the Extended Stellar Halos of Nearby Galaxies: The Wide-Field PISCeS Survey

open access: yesGalaxies, 2017
The wide-field Panoramic Imaging Survey of Centaurus and Sculptor (PISCeS) investigates the resolved stellar halos of two nearby galaxies (the spiral NGC 253 and the elliptical Centaurus A, D ∼ 4 Mpc) out to a galactocentric radius of 150 kpc ...

Cosmicflows-4

open access: yesThe Astrophysical Journal, 2023
With Cosmicflows- 4, distances are compiled for 55,877 galaxies gathered into 38,065 groups. Eight methodologies are employed, with the largest numbers coming from the correlations between the photometric and kinematic properties of spiral galaxies (TF ...

The Shapes and Ages of Elliptical Galaxies [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 1996
Normally elliptical galaxies are thought to be old, evolved systems, but recently a controversy has arisen over the age of ellipticals. Measurements by Gonzáles (1993, Ph.D. thesis, UCSC) show that the Hβ absorption indices of ellipticals span a range of values.

BerryBox: An affordable computer vision system for postharvest phenotyping of cranberry and other small fruits

open access: yesThe Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Fruit size, shape, color, and percent fruit rot are important quality traits for breeding cranberry (Vaccinium macrocarpon Ait.). Image analysis can be used to measure these traits, but affordable hardware for standardized image capture and integrated user‐friendly software pipelines are lacking.
