A Virgo Environmental Survey Tracing Ionised Gas Emission (VESTIGE).XI. Two dimensional H kinematics of the edge-on ram pressure stripped galaxy NGC 4330

M. M. Sardaneta, P. Amram, A. Boselli +18

Using the VESTIGE survey, a deep narrow-band H imaging survey of the Virgo cluster carried on at the CFHT with MegaCam, we discovered a long diffuse tail of ionised gas in the e…

The Color Gradients of the Globular Cluster Systems in M87 and M49

Yiming Wu, Chengze Liu, Eric W. Peng +8

Combining data from the ACS Virgo Cluster Survey (ACSVCS) and the Next Generation Virgo cluster Survey (NGVS), we extend previous studies of color gradients of the globular cluster…

The Pristine survey -- XV. A CFHT ESPaDOnS view on the Milky Way halo and disc populations

R. Lucchesi, C. Lardo, P. Jablonka +14

We present a one-dimensional, local thermodynamic equilibrium (1D-LTE) homogeneous analysis of 132 stars observed at high-resolution with ESPaDOnS. This represents the largest samp…

Central X-ray point-sources found to be abundant in low-mass, late-type galaxies predicted to contain an intermediate-mass black hole

Alister W. Graham, Roberto Soria, Benjamin L. Davis +5

Building upon three late-type galaxies in the Virgo cluster with both a predicted black hole mass of less than 10 M and a centrally-located X-ray point-source,…

The Cen A galaxy group: dynamical mass and missing baryons

Oliver Müller, Federico Lelli, Benoit Famaey +5

The nearby elliptical galaxy Cen A is surrounded by a flattened system of dwarf satellite galaxies with coherent motions. Using a novel Bayesian approach, we measure the mean rotat…

The Sagittarius stream in Gaia eDR3 and the origin of the bifurcations

P. Ramos, T. Antoja, Z. Yuan +6

The Sagittarius dwarf spheroidal (Sgr) is a dissolving galaxy being tidally disrupted by the Milky Way (MW). Its stellar stream still poses serious modelling challenges, which hind…
