We discuss the different physical processes contributing to the infrared continuum of active galactic nuclei (AGNs), assuming that both photoionization from the...

Aims. Soft gamma repeaters (SGRs) are highly magnetised neutron stars (magnetars) notable for their gamma-ray and X-ray outbursts. We used near-infrared (NIR)...

We use images taken with the infrared channel of the Wide Field Camera 3 on the Hubble Space Telescope to study the multiple main sequences (MSs) of NGC 2808...

We present subarcsecond resolution mid-infrared (mid-IR) photometry in the wavelength range from 8 to 20 μm of 18 Seyfert galaxies, reporting high spatial...

The complete mid- to far-infrared continuum energy distribution collected with the Infrared Space Observatory of the Seyfert 2 prototype NGC 5252 is presented...

We use new X-ray data obtained with the Nuclear Spectroscopic Telescope Array (NuSTAR), near-infrared (NIR) fluxes and mid-infrared (MIR) spectra of a sample of...

Over the past decade, several works have used the ratio between total (rest 8‒1000 μm) infrared and radio (rest 1.4 GHz) luminosity in star-forming galaxies (q...

We report on time series Hα profiles of the late B-type supergiant Rigel (beta Orionis A). Our observations indicate the presence of variable and asymmetric...

Eight low-resolution near-infrared spectra (0.8-2.4 μm) of 32522 Thereus were obtained on 2002 August 28 from 0:30 to 5:30 UT, covering more than half of its...
