A Computer Vision Milky Way Compass

open access: yesApplied Sciences, 2023
The Milky Way is used by nocturnal flying and walking insects for maintaining heading while navigating. In this study, we have explored the feasibility of the method for machine vision systems on autonomous vehicles by measuring the visual features and ...

Neocatastrophism and the Milky Way Astrobiological Landscape [PDF]

open access: yesSerbian Astronomical Journal, 2008
The number and distribution of habitable planets in the Milky Way is one of the foremost problems of contemporary astrobiological research. We investigate the effects of applying general neocatastrophic paradigm to the evolution of the Galactic Habitable

Dust Emissivity Variations In the Milky Way [PDF]

open access: yes, 2009
Dust properties appear to vary according to the environment in which the dust evolves. Previous observational indications of these variations in the FIR and submm spectral range are scarce and limited to specific regions of the sky.

The Baryons in the Milky Way Satellites [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, Volume 419, Issue 4, pp. 3304-3318. (MNRAS Homepa, 2011
We investigate the formation and evolution of satellite galaxies using smoothed particle hydrodynamics (SPH) simulations of a Milky Way(MW)-like system, focussing on the best resolved examples, analogous to the classical MW satellites. Comparing with a pure dark matter simulation, we find that the condensation of baryons has had a relatively minor ...

Chemodynamical simulations of the Milky Way galaxy [PDF]

open access: yes, 2011
We present chemodynamical simulations of a Milky-Way-type galaxy using a self-consistent hydrodynamical code that includes supernova feedback and chemical enrichment, and predict the spatial distribution of elements from oxygen to zinc.

Planetary nebulae in the inner Milky Way [PDF]

open access: yes, 2009
New abundances of planetary nebulae located towards the bulge of the Galaxy are derived based on observations made at LNA (Brazil). We present accurate abundances of the elements He, N, S, O, Ar, and Ne for 56 PNe located towards the galactic bulge.

The Role of Mass and Environment on Satellite Distributions around Milky Way Analogs in the Romulus25 Simulation

open access: yesThe Astrophysical Journal, 2023
We study satellite counts and quenched fractions for satellites of Milky Way analogs in Romulus25 , a large-volume cosmological hydrodynamic simulation.

Weighing the Milky Way

open access: yes, 2002
We describe an experiment to measure the mass of the Milky Way galaxy. The experiment is based on calculated light travel times along orthogonal directions in the Schwarzschild metric of the Galactic center. We show that the difference is proportional to

The outer rotation curve of the Milky Way [PDF]

open access: yes, 1996
A straightforward determination of the circular-speed curve vc(R) of the Milky Way suggests that near the Sun, vc starts to rise approximately linearly with R.

The connection between the host halo and the satellite galaxies of the Milky Way [PDF]

open access: yes, 2016
Many properties of the Milky Way's dark matter halo, including its mass assembly history, concentration, and subhalo population, remain poorly constrained.
