Inflation without gauge redundancy
Alfredo Urbano
In the context of gauge theories, observable quantities, if properly defined and computed, do not depend on the gauge-fixing procedure. In this paper, we develop a formalism that i…
Search for 7Be in the outburst of four recent novae
Paolo Molaro, Luca Izzo, Piercarlo Bonifacio +3
Following the recent detection of 7Be in the outburst spectra of Classical Novae we report the search for this isotope in the outbursts of four recent bright novae by means of high…
The STRong lensing Insights into the Dark Energy Survey (STRIDES) 2017/2018 follow-up campaign: Discovery of 10 lensed quasars and 10 quasar pairs
C. Lemon, M. W. Auger, R. McMahon +65
We report the results of the STRong lensing Insights from the Dark Energy Survey (STRIDES) follow-up campaign of the late 2017/early 2018 season. We obtained spectra of 65 lensed q…
Galactic archaeology at high redshift: inferring the nature of GRB host galaxies from abundances
Marco Palla, Francesca Matteucci, Francesco Calura +1
We identify the nature of high redshift long Gamma-Ray Bursts (LGRBs) host galaxies by comparing the observed abundance ratios in the interstellar medium with detailed chemical evo…
Galaxy sizes and the galaxy-halo connection -- I: the remarkable tightness of the size distributions
Lorenzo Zanisi, Francesco Shankar, Andrea Lapi +6
The mass and structural assembly of galaxies is a matter of intense debate. Current theoretical models predict the existence of a linear relationship between galaxy size () an…
Non-linear damping of superimposed primordial oscillations on the matter power spectrum in galaxy surveys
Mario Ballardini, Riccardo Murgia, Marco Baldi +2
Galaxy surveys are an important probe for superimposed oscillations on the primordial power spectrum of curvature perturbations, which are predicted in several theoretical models o…
Calibration of systematics in constraining modified gravity models with galaxy cluster mass profiles
L. Pizzuti, B. Sartoris, S. Borgani +1
Joint lensing and dynamical mass profile determinations of galaxy clusters are an excellent tool to constrain modification of gravity at cosmological scales. However, search for ti…
Milky Way Satellite Census. II. Galaxy--Halo Connection Constraints Including the Impact of the Large Magellanic Cloud
E. O. Nadler, R. H. Wechsler, K. Bechtol +63
The population of Milky Way (MW) satellites contains the faintest known galaxies and thus provides essential insight into galaxy formation and dark matter microphysics. Here we com…
Milky Way Satellite Census. I. The Observational Selection Function for Milky Way Satellites in DES Y3 and Pan-STARRS DR1
A. Drlica-Wagner, K. Bechtol, S. Mau +55
We report the results of a systematic search for ultra-faint Milky Way satellite galaxies using data from the Dark Energy Survey (DES) and Pan-STARRS1 (PS1). Together, DES and PS1…
CODEX clusters. The Survey, the Catalog, and Cosmology of the X-ray Luminosity Function
A. Finoguenov, E. Rykoff, N. Clerc +17
Large area catalogs of galaxy clusters constructed from ROSAT All Sky Survey provide the base for our knowledge on the population of clusters thanks to the long-term multiwavelengt…
Proton-synchrotron as the radiation mechanism of the prompt emission of GRBs?
G. Ghisellini, G. Ghirlanda, G. Oganesyan +6
We discuss the new surprising observational results that indicate quite convincingly that the prompt emission of Gamma-Ray Bursts (GRBs) is due to synchrotron radiation produced by…
Geodesically complete black holes
Raúl Carballo-Rubio, Francesco Di Filippo, Stefano Liberati +1
The 1965 Penrose singularity theorem demonstrates the utterly inevitable and unavoidable formation of spacetime singularities under physically reasonable assumptions, and it remain…
The Three Hundred Project: correcting for the hydrostatic-equilibrium mass bias in X-ray and SZ surveys
S. Ansarifard, E. Rasia, V. Biffi +8
Accurate and precise measurements of masses of galaxy clusters are key to derive robust constraints on cosmological parameters. Rising evidence from observations, however, confirms…
Cosmological Simulation of Galaxy Groups and Clusters-I: Global Effect of Feedback from Active Galactic Nuclei
Rudrani Kar Chowdhury, Suchetana Chatterjee, Anto . I. Lonappan +2
In this study we quantify the properties of the gas and dark matter around active galactic nuclei (AGN) in simulated galaxy groups and clusters and analyze the effect of AGN feedba…
Impact of AGN feedback on galaxies and their multiphase ISM across cosmic time
Milena Valentini, Giuseppe Murante, Stefano Borgani +6
We present simulations of galaxy formation, based on the GADGET-3 code, in which a sub-resolution model for star formation and stellar feedback is interfaced with a new model for A…
Measurement of the Cosmic Microwave Background Polarization Lensing Power Spectrum from Two Years of POLARBEAR Data
Mario Aguilar Faúndez, Kam Arnold, Carlo Baccigalupi +48
We present a measurement of the gravitational lensing deflection power spectrum reconstructed with two seasons cosmic microwave background polarization data from the POLARBEAR expe…
Chemical evolution of ultra-faint dwarf galaxies: testing the IGIMF
E. Lacchin, F. Matteucci, F. Vincenzo +1
We test the integrated galactic initial mass function (IGIMF) on the chemical evolution of 16 ultra-faint dwarf (UFD) galaxies discussing in detail the results obtained for three o…
Blinding multi-probe cosmological experiments
J. Muir, G. M. Bernstein, D. Huterer +62
The goal of blinding is to hide an experiment's critical results -- here the inferred cosmological parameters -- until all decisions affecting its analysis have been finalised. Thi…
Cosmology dependence of galaxy cluster scaling relations
Priyanka Singh, Alex Saro, Matteo Costanzi +1
The abundance of galaxy clusters as a function of mass and redshift is a well known powerful cosmological probe, which relies on underlying modelling assumptions on the mass-observ…

V. Grisoni, G. Cescutti, F. Matteucci +3
We study the chemical evolution of Zr, La, Ce and Eu in the Milky Way discs and bulge by means of chemical evolution models compared with recent spectroscopic data. We consider det…
Schwarzschild geometry counterpart in semiclassical gravity
Julio Arrechea, Carlos Barceló, Raúl Carballo-Rubio +1
