On the galaxy stellar mass function, the massmetallicity relation and the implied baryonic mass function [PDF]
Monthly Notices of the Royal Astronomical Society, 2008 A comparison between published field galaxy stellar mass functions (GSMFs) shows that the cosmic stellar mass density is in the range 4–8 per cent of the baryon density (assuming Ωb= 0.045 ). There remain significant sources of uncertainty for the dust correction and underlying stellar mass-to-light ratio even assuming a reasonable universal stellar ...

Information Volume of Mass Function [PDF]
INTERNATIONAL JOURNAL OF COMPUTERS COMMUNICATIONS & CONTROL, 2020 Given a probability distribution, its corresponding information volume is Shannon entropy. However, how to determine the information volume of a given mass function is still an open issue. Based on Deng entropy, the information volume of mass function is

Multifractal analysis of mass function. [PDF]
Soft comput, 2023 In order to explore the fractal characteristic in Dempster-Shafer evidence theory, a fractal dimension of mass function is proposed recently, to reveal the invariance of scale of belief entropy. When mass function degenerates to probability, the fractal dimension is equivalent to classical Renyi information dimension only with α=1, which can measure ...

On the variation of the initial mass function [PDF]
Monthly Notices of the Royal Astronomical Society, 2000 A universal initial mass function (IMF) is not intuitive, but so far no convincing evidence for a variable IMF exists. The detection of systematic variations of the IMF with star-forming conditions would be the Rosetta Stone for star formation. In

Information fractal dimension of mass function [PDF]
Fractals, 2021 Fractal plays an important role in nonlinear science. The most important parameter to model fractal is fractal dimension. Existing information dimension can calculate the dimension of probability distribution.

Evidence for Initial Mass Function Variation in Massive Early-Type Galaxies
Annual Review of Astronomy and Astrophysics, 2020 The initial mass function (IMF), describing the distribution of birth masses of stars, plays a pivotal role in establishing the observable properties of galaxies.

The ALFALFA H i mass function: a dichotomy in the low-mass slope and a locally suppressed ‘knee’ mass [PDF]
Monthly Notices of the Royal Astronomical Society, 2018 The authors acknowledge the work of the entire ALFALFA collaboration in observing, flagging, and extracting the catalogue of galaxies that this paper makes use of.

Quantum model of mass function
International Journal of Intelligent Systems, 2019 Dempster‐Shafer (D‐S) evidence theory has been used in many fields due to the flexibility and effectiveness in modelling uncertainties, which is the extension of classical probability.

Galaxy And Mass Assembly (GAMA): the galaxy stellar mass function to z = 0.1 from the r-band selected equatorial regions [PDF]
Monthly Notices of the Royal Astronomical Society, 2017 We derive the low redshift galaxy stellar mass function (GSMF), inclusive of dust corrections, for the equatorial Galaxy And Mass Assembly (GAMA) dataset covering 180 deg$^2$. We construct the mass function using a density-corrected maximum volume method,

Tidal Disruption Event Demographics with the Zwicky Transient Facility: Volumetric Rates, Luminosity Function, and Implications for the Local Black Hole Mass Function [PDF]
Astrophysical Journal Letters, 2023 We conduct a systematic tidal disruption event (TDE) demographics analysis using the largest sample of optically selected TDEs. A flux-limited, spectroscopically complete sample of 33 TDEs is constructed using the Zwicky Transient Facility over 3 yr ...
