Exploring galaxies-gravitational waves cross-correlations as an astrophysical probe [PDF]
Journal of Cosmology and Astroparticle Physics, 2020 Gravitational waves astronomy has opened a new opportunity to study the Universe. Full exploitation of this window can especially be provided by combining data coming from gravitational waves experiments with luminous tracers of the Large Scale Structure, like galaxies.

The Many Routes to AGN Feedback [PDF]
, 2017 The energy released by Active Galactic Nuclei (AGN) in the form of radiation, winds, or radio plasma jets, is known to impact on the surrounding interstellar medium. The result of these processes, known as AGN (negative) feedback, is suggested to prevent

High Energy Neutrino Emission from Astrophysical Jets in the Galaxy [PDF]
Advances in High Energy Physics, 2015 We address simulated neutrino emission originated from astrophysical jets of compact objects within the Galaxy. These neutrinos are of high energies (Eνof the order up to a few TeV) and for their observation specialized instruments are in operation, both on Earth and in orbit.

Tracing Ghost Cavities with Low Frequency Radio Observations [PDF]
, 2006 We present X-ray and multi-frequency radio observations of the central radio sources in several X-ray cavity systems. We show that targeted radio observations are key to determining if the lobes are being actively fed by the central AGN.

Astrophysical tests of modified gravity: the morphology and kinematics of dwarf galaxies [PDF]
Journal of Cosmology and Astroparticle Physics, 2013 This paper is the third in a series on tests of gravity using observations of stars and nearby dwarf galaxies. We carry out four distinct tests using published data on the kinematics and morphology of dwarf galaxies, motivated by the theoretical work of Hui et al. (2009) and Jain and Vanderplas (2011). In a wide class of gravity theories a scalar field

Tracing the Mass-Assembly History of Galaxies with Deep Surveys
, 2007 We use the optical and near-infrared galaxy samples from the Munich Near-Infrared Cluster Survey (MUNICS), the FORS Deep Field (FDF) and GOODS-S to probe the stellar mass assembly history of field galaxies out to z ~ 5.

Observations of Lenticular Galaxies at the 6-m Telescope of the Special Astrophysical Observatory [PDF]
GROUND-BASED ASTRONOMY IN RUSSIA. 21ST CENTURY. Proceedings of the All-Russian Conference, 2020 This is a historical review covering the last 30 years of the observational study of lenticular galaxies at the 6m telescope BTA of the Special Astrophysical Observatory of the Russian Academy of Sciences. The development of spectroscopic techniques at the BTA has allowed to get comprehensive information about this class of stellar systems, starting ...

The astrophysical consequences of intervening galaxy gas on fast radio bursts [PDF]
Monthly Notices of the Royal Astronomical Society, 2017 We adopt and analyze results on the incidence and physical properties of damped Ly$ $ systems (DLAs) to predict the astrophysical impact of gas in galaxies on observations of Fast Radio Bursts (FRBs). Three DLA measures form the basis of this analysis: (i) the HI column density distribution, parameterized as a double power-law; (ii) the incidence of ...
