Evidence of distant spiral arms in the Galactic disk quadrant IV from VVV red clump giants
(2022-09-09)
The discovery of new clear windows in the Galactic plane using the VVV near-IR extinction maps allows the study of the structure of the Milky Way (MW) disk. The ultimate goal of this work is to map the spiral arms in the ...
Large amplitude periodic outbursts and long period variables in the VVV VIRAC2-$β$ database
(2022-03-21)
The VISTA Variables in the Via Lactea (VVV) survey obtained near-infrared photometry toward the Galactic bulge and the southern disc plane for a decade (2010 - 2019). We designed a modified Lomb-Scargle method to search ...
