High-z Stellar Masses Can Be Recovered Robustly with JWST Photometry

open access: yesAstrophysical Journal Letters
Robust inference of galaxy stellar masses from photometry is crucial for constraints on galaxy assembly across cosmic time. Here, we test a commonly used spectral energy distribution (SED) fitting code using simulated galaxies from the S phinx ^20 ...

No Tension: JWST Galaxies at $z > 10$ Consistent with Cosmological Simulations

open access: yesThe Open Journal of Astrophysics, 2023
Recent observations by JWST have uncovered galaxies in the very early Universe via the JADES and CEERS surveys. These galaxies have been measured to have very high stellar masses with substantial star formation rates.

The Eclipsing Binaries from the LAMOST Medium-resolution Survey. III. A High-precision Empirical Stellar Mass Library

open access: yesThe Astronomical Journal, 2023
High-precision stellar masses and radii measured directly from binaries can effectively calibrate stellar models. However, such a database containing full spectral types and a large range of metallicity is still not fully established. A continuous effort

Can Protostellar Outflows Set Stellar Masses?

open access: yesThe Astrophysical Journal, 2023
The opening angles of some protostellar outflows appear too narrow to match the expected core–star mass efficiency (SFE) = 0.3–0.5, if the outflow cavity volume traces outflow mass, with a conical shape and a maximum opening angle near 90°.

A New Wide-field Infrared Survey Explorer Calibration of Stellar Mass

open access: yesThe Astrophysical Journal, 2023
We derive new empirical scaling relations between Wide-field Infrared Survey Explorer (WISE) mid-IR (MIR) galaxy photometry and well-determined stellar masses from spectral energy distribution modeling of a suite of optical–infrared photometry provided ...

Early Results from GLASS-JWST. XI. Stellar Masses and Mass-to-light Ratio of z > 7 Galaxies

open access: yesThe Astrophysical Journal Letters, 2023
We exploit James Webb Space Telescope (JWST) NIRCam observations from the GLASS-JWST-Early Release Science program to investigate galaxy stellar masses at z > 7.

LATIS: The Stellar Mass–Metallicity Relation of Star-forming Galaxies at z ∼ 2.5

open access: yesThe Astrophysical Journal, 2023
We present the stellar mass–stellar metallicity relation for 3491 star-forming galaxies at 2 ≲ z ≲ 3 using rest-frame far-ultraviolet spectra from the Ly α Tomography IMACS Survey (LATIS).

Benchmarking pre-main sequence stellar evolutionary tracks using disk-based dynamical stellar masses

open access: yesAstronomy & Astrophysics
Stellar masses are a fundamental property to understand models of pre-main sequence evolution, but their values derived from Hertzsprung–Russell (HR) diagrams are strongly model dependent.

Parameterization of long-period eclipsing binaries

open access: yesOpen Astronomy, 2022
One of the important sources for independent determination of stellar masses is eclipsing binaries with components on the main sequence, and with observable spectral lines of both components.

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...
