The total mass of the Large Magellanic Cloud from its perturbation on the Orphan stream

D. Erkal, V. Belokurov, C. F. P. Laporte +13

In a companion paper by Koposov et al., RR Lyrae from \textit{Gaia} Data Release 2 are used to demonstrate that stars in the Orphan stream have velocity vectors significantly misal…

Piercing the Milky Way: an all-sky view of the Orphan Stream

S. E. Koposov, V. Belokurov, T. S. Li +13

We use astrometry, broad-band photometry and variability information from the Data Release 2 of ESA's Gaia mission (GDR2) to identify members of the Orphan Stream (OS) across the w…

Dark matter-baryon scaling relations from Einasto halo fits to SPARC galaxy rotation curves

Amir Ghari, Benoit Famaey, Chervin Laporte +1

Dark matter-baryon scaling relations in galaxies are important in order to constrain galaxy formation models. Here, we provide a modern quantitative assessment of those relations,…

A-type stars in the Canada-France Imaging Survey II. Tracing the height of the disc at large distances with Blue Stragglers

Guillaume F. Thomas, Chervin F. P. Laporte, Alan W. McConnachie +7

We present the kinematics of Blue Straggler (BS) stars identified in the Canada-France-Imaging-Survey (CFIS), covering 4000 deg on the sky in the -band. The BS sample, chara…

Footprints of the Sagittarius dwarf galaxy in the data set

Chervin F. P. Laporte, Ivan Minchev, Kathryn V. Johnston +1

We analyse an N-body simulation of the interaction of the Milky Way (MW) with a Sagittarius-like dSph (Sgr), looking for signatures which may be attributed to its orbital history i…

Reconciling mass-estimates of ultra-diffuse galaxies

Chervin F. P. Laporte, Adriano Agnello, Julio F. Navarro

The virial masses of ultra-diffuse galaxies (UDGs) have been estimated using the kinematics and abundance of their globular cluster populations, leading to disparate results. Some…
