We shortly present here the ongoing project by the Stockholm supernova group
about the search of high-z supernovae with the ALFOSC camera at the Nordic Optical
Telescope by using galaxy clusters as gravitational telescope.

Aims. We present a ground-based, near-infrared search for lensed supernovae behind the massive cluster Abell 1689 at z = 0.18, which is one of the most powerful gravitational telescopes that nature provides.
Methods. Our survey was based on multi-epoch J-band observations with the HAWK-I instrument ...

The NIR data were obtained with the High Acuity Wide field K-band imager mounted on the VLT (Programmes ID 082.A-0431, 0.83.A-0398, 090.A-0492, 091.A-0108, P.I. Goobar). The HAWK-I has an array of four 2048x2048 HgCdTe detectors covering a total area of 7.5'x7.5' with a sampling of 0.106"/pix per pi ...

Context. The light from distant supernovae (SNe ) can be magnified through gravitational lensing when a foreground galaxy is
located along the line of sight. This line-up allows for detailed studies of SNe at high redshift that otherwise would not be possible.
Spectroscopic observations of lensed ...

Gravitational lenses such as galaxies and galaxy clusters, can magnify the flux of background galaxies. These galaxies at high redshift can host supernovae (SNe) which, thanks to the magnification boost due to lensing, can be observed, otherwise too faint to be detected by current telescopes. Under ...

We report the detection of a young supernova, designated as iPTF16auf, at RA=14:31:09.26 and Dec=+27:14:09.8 (J2000), in the vicinity of the star forming galaxy MRK 685 at spectroscopic redshift 0.015.

Looking at the pinking of a sky at sunset we see a delicate impressionist watercolor or rather the spectacular effect of the refraction of the sun on the particles of the atmosphere? Can the extraordinary geometries of the cubic lattices of a salt crystal be considered a perfect composition deservin ...

The cosmic microwave background radiation discovered by Penzias and Wilson in 1965, is considered one of the most important experimental evidences in favour of the Hot Big Bang standard cosmological model. This radiation provides an image of the Universe when it was about 380,000 years old and has a ...
