Periodic variability of the z=2.0 quasar QSO B1312+7837
M. Minev, V. D. Ivanov, T. Trifonov +6
We report here the first results from a 15-yr long variability monitoring of the z=2.0 quasar QSO B1312+7837. It shows luminosity changes with a period P~6.13 yr (P~2.04 yr at rest…
Near-infrared spectroscopic indices for unresolved stellar populations. II. Index measurements
D. Gasparri, L. Morelli, V. D. Ivanov +7
We measured the equivalent width of a large set of near-infrared (NIR, 0.8--2.4m) line-strength indices in the XShooter medium-resolution spectra of the central regions of 14…
VVV-WIT-04: an extragalactic variable source caught by the VVV Survey
Roberto K. Saito, Dante Minniti, Valentin D. Ivanov +8
We report the discovery of VVV-WIT-04, a near-infrared variable source towards the Galactic disk located ~0.2 arcsec apart from the position of the radio source PMN J1515-5559. The…
