Determining the redshift of astronomical sources is fundamental for cosmological studies, since it allows deriving distances to the observer. However, the distance-redshift relationship commonly used is obtained from the isotropic, homogeneous Friedmann-Lemaitre-Robertson-Walker (FLRW) metric. By fitting this distance-redshift relations to

We report the detection of diffuse radio emission which might be connected to a large-scale filament of the cosmic web covering a 8° × 8° area in the sky, likely associated with a z ≈ 0.1 overdensity traced by nine massive galaxy clusters. In this work, we present radio observations of this region taken with the Sardinia Radio Telescope. Two of the

We report on our program for multiband photometry observations of Optical Transients of Gamma-Ray Bursts at the 152 cm telescope in Loiano. 40 Km south of Bologna, Italy. Observations in the four semesters starting on July 1st, 2001, were performed for 13 events and allowed positive detections for six of them.

In this talk, I present the recent data analysis of the COSMOSOMAS experiment. The COSMOSOMAS experiment is placed at the Observatorio del Teide (Tenerife, 2400 m). It observes the sky with 5 channels between 10 and 17 GHz, covering a daily sky region of ca. 7000 squared degrees, with an angular resolution of 1 degree. Its aim is the study of CMB
