The ESO-VLT MIKiS Survey Reloaded: Exploring the Internal Kinematics of NGC 6440 by Silvia Leanza, Cristina Pallanca, Francesco R. Ferraro, Barbara Lanzoni, Emanuele Dalessandro, Mario Cadelano, Enrico Vesperini, Livia Origlia, Alessio Mucciarelli, Elena Valenti

“…In the context of the ESO-VLT Multi-Instrument Kinematic Survey of Galactic globular clusters, here we present the line-of-sight velocity dispersion profile of NGC 6440, a massive globular cluster located in the Galactic bulge. By combining the data acquired with four different spectrographs, we obtained the radial velocity of a sample of ∼1800 individual stars distributed over the entire cluster extension, from ∼0.″1 to 778″ from the center. …”

“…One of the three unambiguous planets, OGLE-2017-BLG-1275, is the first AnomalyFinder discovery that has a Spitzer microlens parallax measurement, π _E ≃ 0.045 ± 0.015, implying that this planetary system almost certainly lies in the Galactic bulge. In the order listed, the four planetary events have planet-host mass ratios q and normalized projected separations s of $(\mathrm{log}q,s)=(-2.31,0.61)$ , (−2.06, 0.63/1.09), (−2.10, 1.04), and (−2.86, 0.72). …”

Spiral Galaxies in the SAURON Survey by Peletier, R, Ganda, K, Falcon-Barroso, J, Bacon, R, Cappellari, M, Davies, R, Zeeuw, P, Emsellem, E, Krajnovic, D, Kuntschner, H, McDermid, R, Sarzi, M, Ven, G

“…Using 2-dimensional maps of their stellar radial velocity, velocity dispersion, and absorption line strength, it is now much easier to understand the nature of nearby galactic bulges. We discuss a few highlights of this work, and point out some new ideas about the formation of galactic bulges.…”
