Constraining the shape of dark matter haloes using only starlight II. Tests of the technique with objects of known gravitational potential
Jorge Sanchez Almeida, Angel R. Plastino, Sergio Guerra Arencibia +2
The paper validates a photometry‑based Eddington Inversion Method (EIM‑tool) that tests whether observed stellar distributions are physically consistent with cuspy or cored dark‑ma…
A very rapidly rotating white dwarf in nova YZ Reticuli
G. J. M. Luna, N. Rawat, R. Angeloni +4
YZ Ret (Nova Reticuli 2020) is the first VY Scl-type nova-like variable observed to undergo a classical nova eruption. Following the outburst, timing analysis of 20-s cadence TESS…
The slow evolution of dark matter halos from cusp to core naturally produces extended stellar core-like distributions
Jorge Sanchez Almeida, Angel R. Plastino, Ignacio Trujillo
Motivated by the observation of extended stellar cores in dark matter (DM) dominated dwarf galaxies, this study investigates a simple mechanism by which stellar cores can form as a…
Thackeray's globules in IC 2944: the rocket effect revisited by ALMA
M. Fernández-López, L. A. Zapata, B. Reipurth +4
The prominent Thackeray's globules are a collection of cloudlets seen in silhouette against the bright emission of the IC 2944 HII region, ionized by the Collinder 249 cluster of e…
Constraining the shape of dark matter haloes using only starlight. I. A new technique and its application to the galaxy Nube
Jorge Sanchez Almeida, Ignacio Trujillo, Mireia Montes +1
We present a new technique to constrain the gravitational potential of a galaxy from the observed stellar mass surface density alone under a number of assumptions. It uses the clas…
