Computation of a possible Tunguska's strewn field

Albino Carbognani, Mario Di Martino, Giovanna Stirpe

On June 30, 1908, at about 0h 14.5m UTC, the Tunguska Event (TE) occurred, most likely caused by the fall of a small stony asteroid of about 50-80 meters in diameter over the basin…

Optical and UV properties of a radio-loud and a radio-quiet Population A quasar at high redshift

Alice Deconto-Machado, Ascensión del Olmo, Paola Marziani +2

Different properties of quasars may be observed and analysed through the many ranges of the electromagnetic spectrum. Pioneering studies showed that an "H-R diagram" for quasars wa…

Physical characterization of the active asteroid (6478) Gault

Albino Carbognani, Alberto Buzzoni, Giovanna Stirpe

We report dense lightcurve photometry, colors and phase - mag curve of (6478) Gault, an active asteroid with sporadic comet-like ejection of dust. We collected optical ob…

Luminous efficiency based on FRIPON meteors

Esther Drolshagen, Theresa Ott, Detlef Koschny +36

In meteor physics the luminous efficiency is used to convert the meteor's magnitude to the corresponding meteoroid's mass. However, lack of sufficiently accurate verification m…

The quasar main sequence and its potential for cosmology

P. Marziani, D. Dultzin, A. Del Olmo +10

The main sequence offers a method for the systematization of quasar spectral properties. Extreme FeII emitters (or extreme Population A, xA) are believed to be sources accreting ma…

Extreme quasars as distance indicators in cosmology

D. Dultzin, P. Marziani, J. A. de Diego +7

Quasars accreting matter at very high rates (known as extreme Population A [xA] quasars, possibly associated with super-Eddington accreting massive black holes) may provide a new c…
