Gradients of metallicity and age of stars in the dwarf spheroidal galaxies KKs3 and ESO269-66
M. E. Sharina, L. N. Makarova, D. I. Makarov
We compare the properties of the stellar populations of the globular clusters and field stars in two dwarf spheroidal galaxies (dSphs): ESO269-66, a near neighbor of the giant S0 g…
The LMC impact on the kinematics of the Milky Way satellites: clues from the running solar apex
Dmitry Makarov, Sergey Khoperskov, Danila Makarov +3
Dwarf galaxies provide a unique opportunity for studying the evolution of the Milky Way (MW) and the Local Group as a whole. Analysing the running solar apex based on the kinematic…
Arp 58 and Arp 68: two M 51- type systems
Anatoly V. Zasov, Anna S. Saburova, Oleg V. Egorov +2
We study two M 51-type systems Arp 68 and Arp 58, which strongly differ by their stellar masses, gas content and environment. Long-slit spectral observations obtained at the 6-m te…
KDG 64: a large dwarf spheroidal or a small ultradiffuse satellite of Messier 81
Anton V. Afanasiev, Igor V. Chilingarian, Kirill A. Grishin +5
Low-mass early-type galaxies, including dwarf spheroidals (dSph) and brighter dwarf ellipticals (dE), dominate the galaxy population in groups and clusters. Recently, an additional…
Once in a blue stream: Detection of recent star formation in the NGC 7241 stellar stream with MEGARA
David Martinez-Delgado, Santi Roca-Fabrega, Armando Gil de Paz +23
In this work we study the striking case of a narrow blue stream around the NGC 7241 galaxy and its foreground dwarf companion. We want to figure out if the stream was generated by…
HI 21 cm observation and mass models of the extremely thin galaxy FGC 1440
K. Aditya, Peter Kamphuis, Arunima Banerjee +4
We present observations and models of the kinematics and distribution of neutral hydrogen (HI) in the superthin galaxy FGC 1440 with an optical axial ratio . Using the…
