The global mass functions of 35 Galactic globular clusters - II. Clues on the initial mass function and black hole retention fraction [PDF]

, 2017
In this paper, we compare the mass function slopes of Galactic globular clusters recently determined by Sollima & Baumgardt with a set of dedicated N-body simulations of star clusters containing between 65 000 and 200 000 stars.

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).

The Impact of Binaries on the Stellar Initial Mass Function [PDF]

The Impact of Binary Stars on Stellar Evolution, 2018
(abridged) The stellar initial mass function (IMF) can be conveniently represented as a canonical two-part power law function and is largely invariant for star formation regions evident in the Local Group of galaxies. The IMF is a hilfskonstrukt. It is a

Constraining the Initial Mass Function in the Epoch of Reionization from Astrophysical and Cosmological Data

Universe
We aim to constrain the stellar initial mass function (IMF) during the epoch of reionization. To this purpose, we build up a semi-empirical model for the reionization history of the Universe based on various ingredients: the latest determination of the ...

A Census of the Stellar Populations in the Sco-Cen Complex

The Astronomical Journal, 2021
I have used high-precision photometry and astrometry from the early installment of the third data release of Gaia (EDR3) to perform a survey for members of the stellar populations within the Sco-Cen complex, which consist of Upper Sco, UCL/LCC, the V1062

The Initial Mass Function of the First Stars Inferred from Extremely Metal-poor Stars [PDF]

, 2018
We compare the elemental abundance patterns of ∼200 extremely metal-poor (EMP; [Fe/H] < −3) stars to the supernova yields of metal-free stars, in order to obtain insights into the characteristic masses of the first (Population III or Pop III) stars in ...

Cerebrospinal Fluid Liquid Biopsy Enables Targeted Therapy Without Tissue Diagnosis in Pediatric Low‐Grade Gliomas With BRAF V600E Mutation

Pediatric Blood &Cancer, EarlyView.
ABSTRACT We present two pediatric cases of pediatric low‐grade gliomas (PLGG) with BRAF V600E mutations diagnosed and monitored using cerebrospinal fluid (CSF) liquid biopsy analyzed via digital droplet PCR (ddPCR), without tissue biopsy. Both patients were treated with dabrafenib and trametinib and monitored through clinical assessments, magnetic ...
