Lightning produces electromagnetic fields and waves in all frequency ranges. In the
extremely low frequency (ELF) range below 100 Hz, the global Schumann Resonances (SR) …

Schumann resonances (SR) are the electromagnetic oscillations of the spherical cavity
bounded by the electrically conductive Earth and the conductive but dissipative lower …

We present the results of the Fermi-Large Area Telescope 10 yr long light curve (LC)
modeling of selected blazars: six flat-spectrum radio quasars (FSRQs) and five BL Lacertae …

We present the Hylaty geophysical station, a high-sensitivity and low-noise facility for
extremely low frequency (ELF, 0.03–300 Hz) electromagnetic field measurements, which …

The recent discovery of merging black holes suggests that a stochastic gravitational-wave
background is within reach of the advanced detector network operating at design sensitivity …

An inversion algorithm for multistation Schumann resonance measurements is presented
and tested in this paper. The location and intensity of the lightning activity is estimated in …

The importance of lightning has long been recognized from the point of view of climate‐
related phenomena. However, the detailed investigation of lightning on global scales is …

The electromagnetic waves in the Schumann resonance (SR) frequency range (< 100 Hz)
radiated by natural “lightning antennas” excite the Earth‐ionosphere cavity confined …

The lowest region of the ionosphere, the D region, plays an important role in magnetosphere‐
ionosphere coupling but is challenging to directly observe. The group velocity of the …

In the extremely low frequency (ELF) range, the space between the ground and ionosphere
forms a spherical waveguide. When studying the ELF radio-wave propagation on Earth …
