Far-IR Infrared Space Observatory (ISO) maps of four Seyfert galaxies are presented and compared with their optical counterpart images. The far-IR maps resemble...
Far-infrared properties of submillimeter and optically faint radio galaxies
We use deep observations obtained with the Photodetector Array Camera and Spectrometer (PACS) onboard the Herschel Space Observatory to study the far-infrared...
Far-infrared spectroscopy of proteinogenic and other less common amino acids
Far-infrared spectroscopy is a powerful tool complementing the potential of mid-infrared spectroscopy for the search and identification of organic molecules in...
Far-infrared-detected Lyman-break galaxies at z ~ 3. Dust attenuation and dust correction factors at high redshift
Lyman-break galaxies (LBGs) represent one of the kinds of star-forming galaxies that are found in the high-redshift universe. The detection of LBGs in the far...
FarNet-II: An improved solar far-side active region detection method
Context. Activity on the far side of the Sun is routinely studied through the analysis of the seismic oscillations detected on the near side using helioseismic...
Fast events and waves in an active region of the Sun observed in Hα with high spatial resolution
Context: We study the chromosphere of an active region of the Sun in the Hα line. Aims: The development of new instrumentation and new methods of data analysis...
Fast horizontal flows in a quiet sun MHD simulation and their spectroscopic signatures
Numerical simulations of solar surface convection have predicted the existence of supersonic horizontal flows in the photospheric granulation. Recently, the...
Fast infrared variability from a relativistic jet in GX 339-4
We present the discovery of fast infrared/X-ray correlated variability in the black hole transient GX 339-4. The source was observed with subsecond time...
Fast infrared winds during the radio-loud and X-ray obscured stages of the black hole transient GRS 1915+105
The black hole transient GRS 1915+105 entered a new phase of activity in 2018, generally characterised by low X-ray and radio fluxes. This phase has only been...
