Uncertainties in the Galactic Dark Matter distribution: An update
Iocco, Fabio; Benito, María; Cuoco, Alessandro
We present here a quantitative estimate of the impact of uncertainties of astrophysical nature on the determination of the dark matter distribution within our Galaxy, the Milky Way. Based on an update of a previous analysis, this work is motivated by recent new determinations of astrophysical quantities of relevance - such as the Galactic paramete…
Yet another test of Radial Acceleration Relation for galaxy clusters
Desai, Shantanu; Pradyumna, S.; Gupta, Sajal +1 more
We carry out a test of the radial acceleration relation (RAR) for galaxy clusters from two different catalogs compiled in literature, as an independent cross-check of two recent analyses, which reached opposite conclusions. The datasets we considered include a Chandra sample of 12 clusters and the X-COP sample of 12 clusters. For both the samples,…
Implications of triangular features in the Gaia skymap for the Caustic Ring Model of the Milky Way halo
Gonzalez, Anthony H.; Chakrabarty, Sankha S.; Sikivie, Pierre +1 more
The Gaia map of the Milky Way reveals a pair of triangular features at nearly symmetric locations on opposite sides of the Galactic Center. In this paper we explore the implications of these features assuming they are manifestations of a caustic ring in the dark matter distribution of the Milky Way halo. The existence of a series of such rings is …
