Connecting the young pulsars in Milky Way globular clusters with white dwarf mergers and the M81 fast radio burst [PDF]
The detections of four apparently young radio pulsars in the Milky Way globular clusters are difficult to reconcile with standard neutron star formation scenarios associated with massive star evolution. Here, we discuss formation of these young pulsars

Evolution of lithium in the Milky Way halo, discs, and bulge [PDF]
In this work, we study the Galactic evolution of lithium by means of chemical evolution models in the light of the most recent spectroscopic data from Galactic stellar surveys.

The influence of nova nucleosynthesis on the chemical evolution of the Galaxy [PDF]
We adopt up-to-date yields of 7Li, 13C, 15N from classical novae and use a well tested model for the chemical evolution of the Milky Way in order to predict the temporal evolution of these elemental species in the solar neighborhood.

Revisiting long-standing puzzles of the Milky Way: the Sun and its vicinity as typical outer disk chemical evolution [PDF]
We present a scenario of the chemical enrichment of the solar neighborhood that solves the G-dwarf problem by taking into account constraints on a larger scale.

The formation and early evolution of the Milky Way [PDF]
In broad outline, the traditional picture for the formation of the Milky Way can be summarized as follows. The proto-galaxy consisted of a slowly rotating cloud of metal-free gas that cooled by bremsstrahlung and recombination radiation. As the internal pressure of the gas decreased, it collapsed in stages with smaller dimensions, faster rotation ...

Chemo-spectrophotometric evolution of spiral galaxies: I. The model and the Milky Way [PDF]
The chemical and spectro-photometric evolution of spiral galaxies is investigated with detailed models, making use of up-to-date ingredients (like metallicity dependent stellar properties) and a prescription for the star formation rate (SFR) justified ...

The Tilt of the Velocity Ellipsoid of Different Galactic Disk Populations
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 ...

Galactic chemical evolution: Stellar yields and the initial mass function [PDF]
We present a set of 144 Galactic chemical evolution models applied to a Milky Way analogue, computed using four sets of low+intermediate star nucleosynthetic yields, six massive star yield compilations, and six functional forms for the initial mass ...

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