Searching for distant RR Lyrae in the galactic halo using the high cadence transient survey
(Universidad de Chile, 2017)

Using data from the High cadence Transient Survey (HiTS), we inspected the halo of the Milky Way looking for distant RR Lyrae variable stars (dH >100 kpc). The HiTS project, which was originally designed to find supernovae explosions in real time, consists of images taken with the Dark Energy Camera mounted at the Blanco telescope (4 m) at the Cerro Tololo Inter-American Observatory during three different campaigns, covering 200 sq. degrees of the Galactic halo. We identified a total of 332 RR Lyrae stars (173 with data from HiTS 2014, and 159 with HiTS 2015), covering a range in distance from ~ 9 to ~ 260 kpc. According to this study, within our sample of RR Lyrae stars at least 18 are beyond 90 kpc from the Sun (and 16 beyond 100 kpc). The analysis of the catalog allowed us to study the spatial distribution of RR Lyrae stars and to associate three ovendensities with known dwarf spheroidal galaxies (Sextans, Leo~IV y Leo~V). We used this as a proof-of-concept for ideas about the role of RR Lyrae in the discovery of ultra-faint dwarf galaxies that might be difficult to find by other methods. Using the spatial distribution of RR Lyrae from HiTS 2014, we built and analyzed number density profiles of the Milky Way, of the form rho(r) ~ r^{-n}. Following a Markov chain Monte Carlo methodology, we found that the best fit for the data is a simple power law with n=-4.18^{+0.18}_{-0.19}. However, fitting a broken profile is also valid, with a break at R_b=19.34^{+10.66}_{-3.16} kpc, and inner/outer slope of n_1=-3.47^{+2.26}_{-1.32}/n_2=-4.23^{+0.33}_{-0.25}....
