Extremely low mass white dwarfs are very rare objects likely formed in compact binary systems. We present MMT optical spectroscopy of 42 low-mass white dwarf...

In this paper we describe the design and characterization of the optical system of LSPE/Strip, a coherent polarimeter array that will observe the microwave sky...

This work is part of a series of papers describing in detail the design and characterization of the LSPE-STRIP, a microwave telescope operating in the Q- and W...

A sample of 198 soft X-ray-selected active galactic nuclei (AGN) from the ROSAT International X-ray Optical Survey (RIXOS) is used to investigate the X-ray...

We report the results of a CCD investigation of stars in a selected region near the center of the intermediate age galactic cluster NGC 7789. A CM diagram is...

The luminosity function of the globular cluster Palomar 1 is determined together with its confidence interval by applying an adaptive kernel estimator to data...

We computed the luminosity of simulated galaxies of the C-EAGLE project, a suite of 30 high-resolution zoom-in simulations of galaxy clusters based on the EAGLE...

The luminosity-size and mass-size distributions of galaxies out to z~3 are presented. We use very deep near-infrared images of the Hubble Deep Field-South in...

The Earth’s albedo is one of the least studied fundamental climate parameters. The albedo is a bi-directional variable, and there is a high degree of anisotropy...
