Pulsing and non-pulsing ULXs: the iceberg emerges [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT We show that ultraluminous X-ray sources (ULXs) with coherent X-ray pulsing (PULXs) probably have neutron-star spin axes significantly misaligned from their central accretion discs. Scattering in the funnels collimating their emission and producing their apparent super-Eddington luminosities is the most likely origin of the ...

Spectral meta-moments reveal hidden signatures of vortex pulses [PDF]
EPJ Web of Conferences, 2019 Ultrashort vortex pulses possess specific spatio-spectral signatures due to Gouy phase shift. Helical movement of anomalies around the phase singularity was found which is referred to as spectral Gouy rotation. The analysis of spectral moments allows for

On the Nature of Precursors in the Radio Pulsar Profiles
, 2007 In the average profiles of several radio pulsars, the main pulse is accompanied by the preceding component. This so called precursor is known for its distinctive polarization, spectral, and fluctuation properties.

What Do We Hear When We Hear Microbe Sounds
Pulse, 2022 The concept of the Anthropocene, based on the premise that mankind has become a major geological force in its own right, has grown into a central theme with issues such as ecological crisis, climate change, or sustainable futures.

Propagation of a short laser pulse in a plasma [PDF]
, 1997 The propagation of an electromagnetic pulse in a plasma is studied for pulse durations that are comparable to the plasma period. When the carrier frequency of the incident pulse is much higher than the plasma frequency, the pulse propagates without ...

The Soundscape of Man in the Holocene: An Exercise in Sensitization
Pulse, 2022 This paper discusses how the natural soundscape of Max Frisch’s novella Man in the Holocene (1979) affords a contemplation on the inadequacy of human epistemology against the immense temporality of the geological deep time.

Dermatologic Clinics, 2000 High-dose intravenous (i.v.) methylprednisolone has been used therapeutically in a number of medical fields to avoid the complications and side effects of long-term glucocorticoid (GC) therapy and because of the perception that high-dose i.v. methylprednisolone may have "special" therapeutic effects.

Time-resolved optical gating based on dispersive propagation: a new method to characterize optical pulses [PDF]
, 2000 We introduce the technique of time-resolved optical gating (TROG) based on dispersive propagation (DP), a new noninterferometric method for characterizing ultrashort optical pulses in amplitude and phase without the need for a short optical gating pulse.
