A high-velocity star recently ejected by an intermediate-mass black hole in M15
Yang Huang, Qingzheng Li, Jifeng Liu +4
The existence of intermediate-mass black holes (IMBHs) is crucial for understanding various astrophysical phenomena, yet their existence remains elusive, except for the LIGO-Virgo…
A Topological Data Analysis of the CHIME/FRB Catalogues
Shruti Bhatporia, Anthony Walters, Jeff Murugan +1
In this paper, we use Topological Data Analysis (TDA), a mathematical approach for studying data shape, to analyse Fast Radio Bursts (FRBs). Applying the Mapper algorithm, we visua…
Galaxy peculiar velocities in the Zone of Avoidance
K. Said, R. C. Kraan-Korteweg, T. H. Jarrett
Dust extinction and stellar confusion of the Milky Way hinder the detection of galaxies at low Galactic latitude, creating the so-called Zone of Avoidance (ZoA). This has hampered…
RR Lyraes and Type II Cepheids in the Magellanic Clouds: Distance Scales and Population Gradients
Michael Feast
This paper discusses the current uncertainties in luminosity calibration of the RR Lyrae variables. The difference in distance moduli between the SMC and LMC as derived from RR Lyr…
Fisher4Cast Users' Manual
Bruce A. Bassett, Yabebal Fantaye, Renée Hlozek +1
This is the Users' Manual for the Fisher Matrix software Fisher4Cast and covers installation, GUI help, command line basics, code flow and data structure, as well as cosmological a…
Nearby Large-Scale Structures and the Zone of Avoidance: A Conference Summary and Assessment
Anthony Fairall, Ofer Lahav
This conference has brought together many of the world's `cosmographers', particularly those focussed on the mapping nearby large-scale structures. Not surprisingly, numerous portr…
