Welcome to my home page. I'm an astrophycisist currently working at the INAF-IASF Milan.

I received my PHD in January 2004 at the University of Milan Bicocca. I worked as a post-doc from 2004 to 2007 at the University of California Irvine. I then moved to the University of Bologna in 2007 and to IASF in 2008. I'm since January 2017 Staff Researcher at IASF. I have been working on many X-ray satellites (SAX, Chandra, XMM, Suzaku, NuSTAR), I am involved in the calibration and background characterization of XMM and NuSTAR and I am currently active in the design of Athena.

About My Research

I'm an observer interested in the physics of clusters and group of galaxies as inferred mainly by X-ray observations but also from observations at other wavelengths like optical and radio. I work in particular on AGN feedback in cool cores, metal abundances in the intra-cluster and intra-group medium and the characterization of the dynamical state of a system.

Galaxy clusters are also important cosmological tools, provided we are able to measure their masses. This measure can be done in many different ways like for example using their X-ray emission, gravitational lensing or the dynamics of their member galaxies.

Latest Projects

A selection of the latest projects I'm currently working on:

  • Analysis of the data of the CHEX-MATE project
  • Analysis of the X-ray data of the XMM mosaic of NGC 5044

Latest News

  • CHEX-MATE paper on the pressure profiles of 6 objects with PLANCK and SPT submitted to A&A (see here)
  • Paper on a sample of groups observed with Suzaku out to R200 accepted for publication on MNRAS (see here)
  • 3 MeerKAT programs approved as co-I: 2 with PI M. Balboni to observe the CHEX-MATE cluster A2244 (12 hrs, B) and a sample of 6 CHEX-MATE clusters (39 hrs, A) and one to observe A754 (PI Botteon, 20 hrs, A)
  • 2 Chandra programs as co-I awarded in AO24: one to observe the Nest Group (150 ks, PI Simionescu), one to observe a candidate equatorial shock merging cluster MCXC J0928.6+3747 (126 ks, PI Hoang)
  • Paper on the systematics of the Fe-L measurement by our PHD student G.Riva accepted for publication by A&A (see here)
