Transition of the Stellar Initial Mass Function Explored with Binary Population Synthesis [PDF]
, 2013 The stellar initial mass function (IMF) plays a crucial role in determining the number of surviving stars in galaxies, the chemical composition of the interstellar medium, and the distribution of light in galaxies.

Sustainability and Equity Challenges to Pension Systems: The Case of Lebanon
Journal of Banking and Financial Economics, 2018 Reform of Lebanon’s pension system is indispensable. The country already faces fiscal sustainability risks, which will be compounded in the future by significantly higher pension- related spending and liabilities, mainly reflecting adverse demographics ...

Hierarchical Bayesian inference of the Initial Mass Function in Composite Stellar Populations [PDF]
, 2017 The initial mass function (IMF) is a key ingredient in many studies of galaxy formation and evolution. Although the IMF is often assumed to be universal, there is continuing evidence that it is not universal.

Shifting paradigms of thought and power [PDF]
Bezbednosni Dijalozi, 2020 The article argues that a shift in paradigm is required away from the free market. The key question is if we are brave enough to call ourselves collectively and individually to moral and social accountability.

Evidence for a Turnover in the IMF of Low Mass Stars and Sub-stellar Objects: Analysis from an Ensemble of Young Clusters [PDF]
, 2008 We present a combined analysis of the low-mass Initial Mass Function (IMF) for seven star forming regions. We first demonstrate that the ratios of stars to brown dwarfs are consistent with a single underlying IMF.

Dark Matter and IMF normalization in Virgo dwarf early-type galaxies [PDF]
, 2015 In this work we analyze the dark matter (DM) fraction, $f_{DM}$, and mass-to-light ratio mismatch parameter, $\delta_{IMF}$ (computed with respect to a Milky-Way-like IMF), for a sample of 39 dwarf early-type galaxies (dEs) in the Virgo cluster. Both $f_{

MUSE observations of M87: radial gradients for the stellar initial-mass function and the abundance of Sodium [PDF]
, 2017 Based on MUSE integral-field data we present evidence for a radial variation at the low-mass end of the stellar initial-mass function (IMF) in the central regions of the giant early-type galaxy NGC4486 (M87).

A systematic variation of the stellar initial mass function in early-type galaxies [PDF]
, 2012 Much of our knowledge of galaxies comes from analysing the radiation emitted by their stars. It depends on the stellar initial mass function (IMF) describing the distribution of stellar masses when the population formed. Consequently knowledge of the IMF

The Luminosity & Mass Function of the Trapezium Cluster: From B stars to the Deuterium Burning Limit [PDF]
, 2002 We use the results of a new, multi-epoch, multi-wavelength, near-infrared census of the Trapezium Cluster in Orion to construct and to analyze the structure of its infrared (K band) luminosity function.
