A fundamental relation between mass, SFR and metallicity in local and high redshift galaxies [PDF]
, 2010 We show that the mass-metallicity relation observed in the local universe is due to a more general relation between stellar mass M*, gas-phase metallicity and SFR.

The Relation between Fundamental Constants and Particle Physics Parameters
Universe, 2017 The observed constraints on the variability of the proton to electron mass ratio μ and the fine structure constant α are used to establish constraints on the variability of the Quantum Chromodynamic Scale and a combination of the Higgs Vacuum Expectation

HIDE-AND-SEEK WITH THE FUNDAMENTAL METALLICITY RELATION [PDF]
The Astrophysical Journal Letters, 2016 ABSTRACT We use ∼83,000 star-forming galaxies at 0.04 < z < 0.3 from the Sloan Digital Sky Survey to study the so-called fundamental metallicity relation (FMR) and report on the disappearance of its anti-correlation between metallicity and star formation rate (SFR) when using the new metallicity indicator recently proposed by ...

A Fundamental Relation between Compact Stellar Nuclei, Supermassive Black Holes, and Their Host Galaxies [PDF]
, 2006 Imaging surveys with the Hubble Space Telescope (HST) have shown that ≈50%-80% of low- and intermediate-luminosity galaxies contain a compact stellar nucleus at their center, regardless of host galaxy morphological type.

The angular momentum-mass relation: a fundamental law from dwarf irregulars to massive spirals [PDF]
, 2018 In a $\Lambda$CDM Universe, the specific stellar angular momentum ($j_\ast$) and stellar mass ($M_\ast$) of a galaxy are correlated as a consequence of the scaling existing for dark matter haloes ($j_{\rm h}\propto M_{\rm h}^{2/3}$).

New fundamental relation of hyperrings
European Journal of Combinatorics, 2013 We prove that @q^* as previously defined [Int. J. Contemp. Math. Sci. 5 (2010) 721] is the smallest equivalence relation such that the quotient structure R/@q^* is a commutative fundamental ring. We also investigate some properties with respect to the commutative fundamental relation @q^* on a hyperring R.

The Faber–Jackson relation and Fundamental Plane from halo abundance matching [PDF]
, 2016 The Fundamental Plane (FP) describes the relation between the stellar mass, size, and velocity dispersion of elliptical galaxies; the Faber–Jackson relation (FJR) is its projection on to {mass, velocity} space.

From the Tully-Fisher relation to the Fundamental Plane through mergers [PDF]
, 2005 We set up a series of self-consistent N-body simulations to investigate the fundamental plane of merger remnants of spiral galaxies. These last ones are obtained from a theoretical Tully-Fisher relation at z=1, assuming a constant mass-to-light ratio ...

Boolean Rings Based On Multirings [PDF]
Journal of Sciences, Islamic Republic of Iran, 2021 The purpose of this paper is to construct Boolean rings from multirings. In this regards, a method to construct a multigroup(multiring) on a given non-empty set, are introduced and its properties has been investigated.
