Using the Rozhen National Astronomical Observatory (NAO) in Bulgaria, astronomers have performed long-term monitoring of the quasar QSO B1312+7837 and have detected a periodic variability of this source. The finding is reported ...
A team of astronomers from Switzerland and Germany has conducted a long-term multi-band photometric monitoring of a nearby blazar known as Markarian 501. The observational campaign delivered essential information regarding ...
Engineers at Duke University have devised a new approach to using sound waves to manipulate tiny particles suspended in liquid in complex ways. Dubbed a "shadow waveguide," the technique uses only two sound sources to create ...
