Constraining the Initial Mass Function via Stellar Transients

open access: yesUniverse
The stellar initial mass function (IMF) represents a fundamental quantity in astrophysics and cosmology describing the mass distribution of stars from low mass all the way up to massive and very massive stars. It is intimately linked to a wide variety of

The Metal-Poor IMF, Stellar Evolution, and Star Formation Histories [PDF]

open access: yesProceedings of the International Astronomical Union, 2008
AbstractI present an introduction to three important subjects relevant to low metallicity star formation: the IMF, stellar evolution, and star formation histories. I will draw on observations from the LCID (Local Cosmology from Isolated Dwarfs) project to illustrate some of these topics.

Calibrated, cosmological hydrodynamical simulations with variable IMFs III: spatially resolved properties and evolution [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2018
Recent spatially-resolved observations of massive early-type galaxies (ETGs) have uncovered evidence for radial gradients of the stellar initial mass function (IMF), ranging from super-Salpeter IMFs in the centre to Milky Way-like beyond the half-light radius, $r_e$.

Beyond salaries: Teachers' experiences of navigating early years education amid economic instability in Türkiye

open access: yesBritish Educational Research Journal, EarlyView.
Abstract The intersection of economic conditions and early years education has long been debated, particularly where financial constraints shape educational practice and professional realities. Türkiye, characterised by high inflation and structural vulnerabilities in purchasing power parity, provides a critical context for examining how economic ...

The Initial Mass Function of the Galactic Early-type Field Stars Based on the LAMOST Survey

open access: yesThe Astrophysical Journal
Research on the high-mass end of the initial mass function (IMF) has been limited due to a scarcity of samples. Recently, Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST), as the most efficient spectroscopic telescope, has provided new ...

The interplanetary magnetic field influences mid-latitude surface atmospheric pressure

open access: yesEnvironmental Research Letters, 2013
The existence of a meteorological response in the polar regions to fluctuations in the interplanetary magnetic field (IMF) component B _y is well established.

Statistical Activities of IMF: A Factor of Global Financial Stabilization in the Post-Crisis Period

open access: yesСтатистика України, 2018
The areas of transformation of the statistical activities of the International Monetary Fund (IMF) in the post-crisis period are outlined, and their contribution in the global financial stabilization is assessed.

IMF Sovereign Debt Restructuring Framework: Origin, Evolution and Latest Updates of its Main Components

open access: yesRevista Direito GV, 2020
The first introductory manual of the IMF framework for Sovereign Debt Restructurings (SDRs) is introduced in this article. SDR processes, in which billions of dollars are negotiated, constitute key elements for the healthy recovery of an over-indebted ...

Characteristics of merging at the magnetopause inferred from dayside 557.7-nm all-sky images: IMF drivers of poleward moving auroral forms [PDF]

open access: yesAnnales Geophysicae, 2006
We combine in situ measurements from Cluster with high-resolution 557.7 nm all-sky images from South Pole to investigate the spatial and temporal evolution of merging on the dayside magnetopause. Variations of 557.7 nm emissions were observed at a 6 s
