Identification of pulsation modes from spectroscopy
Time-series of high-resolution spectra of massive main-sequence pulsators contain information on the degree l and azimuthal number m of a pulsation mode. I...
Identification of Superclusters and their Properties in the Sloan Digital Sky Survey
Superclusters are the largest massive structures in the cosmic web on tens to hundreds of megaparsecs (Mpc) scales. They are the largest assembly of galaxy...
Identifying the fingerprints of r-process heavy metals in a short GRB
The afterglow of some short GRBs displays a late-time rebrightening, visible in the near-infrared a few days after the burst. This late-time bump could be...
IGR J17091-3624 undergoes 'heartbeat' oscillations similar to those of GRS 1915+105
We report on the follow up observations after the report of ~10 mHz quasi-periodic oscillations (QPO -- ATel #3225) in the X-ray light curve of the ongoing...
We have identified IGR J17303-0601 (1RXS J173021.5-055933) as an intermediate polar (IP). The optical counterpart is USNOA2.0 0825_10606993 (RA=17h30m21.9s Dec=...
The INTEGRAL/EINSTEIN/ROSAT/NVSS objects IGR J17418-12122, 2E 1739.1-1210, 1RXS J174155.3-121157 and NVSS J174155-121201 have recently been suggested to be the...
