    • An atlas of Hubble Space Telescope spectra and images of nearby spiral galaxies 

      Hughes, M.A.; Alonso-Herrero, A.; Axon, D.J.; Scarlata, C.; Atkinson, J.; Batcheldor, D.; Binney, J.; Capetti, A.; Carollo, C.M.; Dressel, L.; Gerssen, J.; Macchetto, F.D.; Maciejewski, W.; Marconi, A.; Merrifield, M.; Ruiz, M.; Sparks, W.; Stiavelli, M.; Tsvetanov, Z.; van der Marel, R. (2003)
      We have observed 54 nearby spiral galaxies with the Space Telescope Imaging Spectrograph (STIS) on the Hubble Space Telescope to obtain optical long-slit spectra of nuclear gas disks and STIS optical ( R band) images of ...

    • The contribution from scattered light to quasar galaxy hosts 

      Young, S.; Axon, D.J.; Robinson, A.; Capetti, A. (2009)
      We present models representing the scattering of quasar radiation off free electrons and dust grains in geometries that approximate the structure of quasar host galaxies. We show that, for reasonable assumptions, scattering ...

    • The LOFAR view of FR0 radio galaxies 

      Capetti, A.; Brienza, M.; Baldi, R. D.; Giovannini, G.; Morganti, R.; Hardcastle, M. J.; Rottgering, H. J. A.; Brunetti, G. F.; Best, P. N.; Miley, G. (2020-10-09)
      We explore the low-frequency radio properties of the sources in the Fanaroff-Riley class 0 catalog (FR0CAT) as seen by the LOw Frequency ARray (LOFAR) observations at 150 MHz. This sample includes 104 compact radio active ...

    • The LOFAR view of giant, early-type galaxies: radio emission from active nuclei and star formation 

      Capetti, A.; Brienza, M.; Balmaverde, B.; Best, R. D. P. N.; Baldi, R. D.; Drabent, A.; Gurkan, G.; Rottgering, H. J. A.; Tasse, C.; Webster, B. (2022-02-17)
      We studied the properties and the origin of the radio emission in the most luminous, early-type galaxies (ETGs) in the nearby Universe (MK ≤ −25, recession velocity ≤7500 km s−1), as seen by the 150 MHz Low-Frequency ARray ...

    • Nuclear Properties of a Sample of Nearby Spiral Galaxies from Hubble Space Telescope STIS Imaging 

      Scarlata, C.; Stiavelli, M.; Hughes, M.A.; Axon, D.J.; Alonso-Herrero, A.; Atkinson, J.; Batcheldor, D.; Binney, J.; Capetti, A.; Carollo, C.M.; Dressel, L.; Gerssen, J.; Macchetto, F.D.; Maciejewski, W.; Marconi, A.; Merrifield, M.; Ruiz, M.; Sparks, W.; Tsvetanov, Z.; van der Marel, R. (2004)

    • Nuclear properties of nearby spiral galaxies from Hubble Space Telescope NICMOS imaging and STIS spectroscopy 

      Hughes, M.A.; Axon, D.J.; Atkinson, J.; Alonso-Herrero, A.; Scarlata, C.; Marconi, A.; Batcheldor, D.; Binney, J.; Capetti, A.; Carollo, C.M.; Dressel, L.; Macchetto, F.D.; Maciejewski, W.; Merrifield, M.; Ruiz, M.; Sparks, W.; Stiavelli, M.; Tsvetanov, Z.; Gerssen, J. (2005)

    • Raining in MKW 3 s: a Chandra-MUSE analysis of X-ray cold filaments around 3CR 318.1 

      Jimenez-Gallardo, A.; Massaro, F.; Balmaverde, B.; Paggi, A.; Capetti, A.; Forman, W. R.; Kraft, R. P.; Baldi, R. D.; Mahatma, V. H.; Mazzucchelli, C.; Missaglia, V.; Ricci, F.; Venturi, G.; Bam, S. A.; Liuzzo, E.; O'Dea, C. P.; Prieto, M. A.; Röttgering, H. J. A.; Sani, E.; Sparks, W. B.; Tremblay, G. R.; Weeren, R. J. van; Wilkes, B. J.; Harwood, J. J.; Mazzotta, P.; Kuraszkiewicz, J. (2021-05-10)
      We present the analysis of X-ray and optical observations of gas filaments observed in the radio source 3CR 318.1, associated with NGC 5920, the Brightest Cluster Galaxy (BCG) of MKW 3s, a nearby cool core galaxy cluster. ...

    • A snapshot of the oldest AGN feedback phases 

      Brienza, M.; Shimwell, T. W.; Gasperin, F. de; Bikmaev, I.; Bonafede, A.; Botteon, A.; Brüggen, M.; Brunetti, G.; Burenin, R.; Capetti, A.; Churazov, E.; Hardcastle, M.

      Active Galactic Nuclei (AGN) inject large amounts of energy into their host galaxies and surrounding environment, shaping their properties and evolution. In particular, AGN jets inflate cosmic-ray lobes, which can rise ...
