, 2018 Observational and theoretical arguments increasingly suggest that the initial mass function (IMF) of stars may depend systematically on environment, yet most galaxy formation models to date assume a universal IMF.

Constraints on a Universal IMF from UV to Near-IR Galaxy Luminosity Densities
, 2003 We obtain constraints on the slope of a universal stellar initial mass function (IMF) over a range of cosmic star-formation histories (SFH) using z=0.1 luminosity densities in the range from 0.2 to 2.2 microns.

The Astrophysical JournalUnlike Earth, Mars lacks a global intrinsic magnetic field but has regional crustal magnetic fields concentrated in its southern hemisphere. This unique configuration leads to distinctive interactions with the solar wind.

Uncertainties in Galactic Chemical Evolution Models [PDF]
, 2016 We use a simple one-zone galactic chemical evolution model to quantify the uncertainties generated by the input parameters in numerical predictions for a galaxy with properties similar to those of the Milky Way.

Constraining the z ∼ 1 Initial Mass Function with HST and JWST Lensed Stars in MACS J0416.1−2403
The Astrophysical JournalOur understanding of galaxy properties and evolution is contingent on knowing the initial mass function (IMF), and yet to date the IMF is constrained only to local galaxies.

The Astrophysical Journal Letters, 2023 Early results from the James Webb Space Telescope (JWST) observations have hinted at two traces beyond the standard cosmological framework. One is the extraordinarily high stellar masses and their density at z = 7.5 ∼ 9.1; another is the unexpected ...

IMF ‐World Bank Cooperation Before and After the Global Financial Crisis
, 2020 This article adopts a diachronic view to compare patterns of institutional evolution of cooperation between the International Monetary Fund (IMF or Fund) and the World Bank (or Bank) before and after the global financial crisis.

Temporal-spatial structure of magnetic merging at the magnetopause inferred from 557.7-nm all-sky images [PDF]
Annales Geophysicae, 2004 We demonstrate that high-resolution 557.7-nm all-sky images are useful tools for investigating the spatial and temporal evolution of merging on the dayside magnetopause.

Influence of upstream solar wind on magnetic field distribution in the Martian nightside ionosphere
Earth and Planetary PhysicsUsing over eight years of Mars Atmosphere and Volatile EvolutioN (MAVEN) data, from November 2014 to May 2023, we have investigated the Martian nightside ionospheric magnetic field distribution under the influence of upstream solar wind drivers ...
