Invariant conserved currents for gravity
Yuri N. Obukhov, Guillermo F. Rubilar
We develop a general approach, based on the Lagrange-Noether machinery, to the definition of invariant conserved currents for gravity theories with general coordinate and local Lor…
Invariant conserved currents in gravity theories: diffeomorphisms and local gauge symmetries
Yuri N. Obukhov, Guillermo F. Rubilar
Previously, we have developed a general method to construct invariant conserved currents and charges in gravitational theories with Lagrangians that are invariant under spacetime d…
On the newly discovered Canes Venatici II dSph galaxy
C. Greco, M. Dall'Ora, G. Clementini +11
We report on the detection of variable stars in the Canes Venatici II (CVn II) dwarf spheroidal galaxy, a new satellite of the Milky Way recently discovered by the Sloan Digital Sk…
Testing the nature of S0 galaxies using planetary nebula kinematics in NGC 1023
E. Noordermeer, M. R. Merrifield, L. Coccato +9
We investigate the manner in which lenticular galaxies are formed by studying their stellar kinematics: an S0 formed from a fading spiral galaxy should display similar cold outer d…
Possible optical detection of a fast, nearby radio pulsar PSR B1133+16
S. V. Zharikov, Yu. A. Shibanov, R. E. Mennickent +1
Aims: We performed deep optical observations of the field of an old, fast-moving radio pulsar PSR B1133+16 in an attempt to detect its optical counterpart and a bow shock nebula. M…
The dark matter halo of NGC 1399 - CDM or MOND?
T. Richtler, Y. Schuberth, M. Hilker +3
Central galaxies in galaxy clusters may be key discriminants in the competition between the cold dark matter (CDM) paradigm and modified Newtonian dynamics (MOND). We investigate t…
