Weighing the Galactic disk in sub-regions of the solar neighbourhood using Gaia DR2
Axel Widmark, Pablo Fernández de Salas, Giacomo Monari
We infer the gravitational potential of the Galactic disk by analysing the phase-space densities of 120 stellar samples in 40 spatially separate sub-regions of the solar neighbourh…
Measuring the Matter Density of the Galactic Disk Using Stellar Streams
Axel Widmark, Khyati Malhan, Pablo F. de Salas +1
We present a novel method for determining the total matter surface density of the Galactic disk by analysing the kinematics of a dynamically cold stellar stream that passes through…
21 cm cosmology and spin temperature reduction via spin-dependent dark matter interactions
Axel Widmark
The EDGES low-band experiment has measured an absorption feature in the cosmic microwave background radiation (CMB), corresponding to the 21 cm hyperfine transition of hydrogen at…
Measuring the local matter density using Gaia DR2
Axel Widmark
We determine the total dynamical matter density in the solar neighbourhood using the second Gaia data release (DR2). The dynamical matter density distribution is inferred in a fram…
Inferring properties of the local white dwarf population in astrometric and photometric surveys
Axel Widmark, Daniel J. Mortlock, Hiranya V. Peiris
The Gaia mission will provide precise astrometry for an unprecedented number of white dwarfs (WDs), encoding information on stellar evolution, Type Ia supernovae progenitor scenari…
