STAR FORMATION RELATIONS IN THE MILKY WAY [PDF]

open access: yesThe Astrophysical Journal, 2016
ABSTRACT The relations between star formation and properties of molecular clouds (MCs) are studied based on a sample of star-forming regions in the Galactic Plane. Sources were selected by having radio recombination lines to provide identification of associated MCs and dense clumps. Radio continuum emission and mid-infrared emission were

The Rapid Onset of Stellar Bars in the Baryon-dominated Centers of Disk Galaxies

open access: yesThe Astrophysical Journal, 2023
Recent observations of high-redshift galactic disks ( z ≈ 1–3) show a strong negative trend in the dark-matter (DM) fraction f _DM with increasing baryon surface density.

The Tilt of the Velocity Ellipsoid of Different Galactic Disk Populations

open access: yesThe Astrophysical Journal, 2023
The tilt of the velocity ellipsoid is a helpful tracer of the gravitational potential of the Milky Way. In this paper, we use nearly 140,000 red clump (RC) stars selected from LAMOST and Gaia to make a detailed analysis of the tilt of the velocity ...

The Imprint of Clump Formation at High Redshift. II. The Chemistry of the Bulge

open access: yesThe Astrophysical Journal, 2023
In Paper I, we showed that clumps in high-redshift galaxies, having a high star formation rate density (Σ _SFR ), produce disks with two tracks in the [Fe/H]–[ α /Fe] chemical space, similar to that of the Milky Way’s (MW’s) thin+thick disks.

The R-Process Alliance: Chemodynamically Tagged Groups. II. An Extended Sample of Halo r-process-enhanced Stars

open access: yesThe Astrophysical Journal, 2023
Orbital characteristics based on Gaia Early Data Release 3 astrometric parameters are analyzed for ∼1700 r -process-enhanced (RPE; [Eu/Fe] > +0.3) metal-poor stars ([Fe/H] ≤ −0.8) compiled from the R -Process Alliance, the GALactic Archaeology with ...

Distant Echoes of the Milky Way’s Last Major Merger

open access: yesThe Astrophysical Journal, 2023
The majority of the Milky Way’s stellar halo consists of debris from our galaxy’s last major merger, the Gaia-Sausage-Enceladus (GSE). In the past few years, stars from the GSE have been kinematically and chemically studied in the inner 30 kpc of our ...

The Milky Way as a Star Formation Engine [PDF]

open access: yes, 2014
The cycling of material from the interstellar medium (ISM) into stars and the return of stellar ejecta into the ISM is the engine that drives the "galactic ecology" in normal spirals, a cornerstone in the formation and evolution of galaxies through cosmic time.

Traces of the formation history of the Milky Way [PDF]

open access: yesProceedings of the International Astronomical Union, 2013
AbstractChemical and kinematical information is needed in order to understand and trace the formation history of our Galaxy. In the homogeneous large sample of F and G stars in the survey by Nordström et al. (2004), groups of stars with orbital parameters different from field stars were found by Helmi et al. (2006).

A transient inflammatory response contributes to oxaliplatin neurotoxicity in mice

open access: yesAnnals of Clinical and Translational Neurology, Volume 9, Issue 12, Page 1985-1998, December 2022., 2022
Abstract Objectives Peripheral neuropathy is a relevant dose‐limiting adverse event that can affect up to 90% of oncologic patients with colorectal cancer receiving oxaliplatin treatment. The severity of neurotoxicity often leads to dose reduction or even premature cessation of chemotherapy.
