Sensitized radiation-induced polymerization of indene monomer was achieved at a dose rate of 3 kGy/h. The sensitizer (1,1,2,2-tetrachloroethane or TCE) leads to higher polyindene yields and faster polymerization kinetics with respect to bulk radiation-induced polymerization of indene. The radiation chemical yield Gp was found to increase with the

We report the discovery of a new black-widow millisecond pulsar, PSR J1544–2555, associated with the Fermi-Large Area Telescope (LAT) source 4FGL J1544.2–2554. Optical, radio, and gamma-ray observations confirmed its nature as a compact spider binary system. Optical photometry from ULTRACAM revealed a $\sim$2.7-h orbital period, guiding MeerKAT

Giant low-surface-brightness (GLSB) galaxies represent an extreme class of disk galaxies characterized by exceptionally large sizes and low stellar densities. Their formation and evolutionary pathways remain poorly constrained, primarily due to the observational challenges associated with detecting their faint stellar disks. In this work, we
