Unveiling BLR Structure in AGN with High Resolution X-Ray Spectra: An Analytic Approach to Wind Emission Line Profiles
Scott Hagen, Chris Done, Gabriele A. Matzeu +1
XRISM has provided an unprecedented view of the emission and absorption lines in the X-ray. Notably, early results showed significant complexity to the Fe-K line profile in AGN,…
Gravitational-wave and electromagnetic detections in the context of the CosmoDC2 LSST synthetic catalog
Ranier Menote, Valerio Marra, Riccardo Sturani +3
We release CosmoDC2_BCO, a synthetic catalog of gravitational-wave events and electromagnetic counterparts associated with galaxies from CosmoDC2. The catalog provides intrinsic an…
Seeking Spinning Subpopulations of Black Hole Binaries via Iterative Density Estimation
Jam Sadiq, Thomas Dent, Ana Lorenzo-Medina
Attempts to understand the formation of binary black hole (BBH) systems detected via gravitational wave (GW) emission are affected by many unknowns and uncertainties, from both the…
A FLASH on Blazars: Capturing the Radio Realm of 4FGL Blazars with SKAO Pathfinders
Meriem Behiri, Elizabeth Mahony, Elaine Sadler +6
This work investigates the multi-wavelength properties of 165 4FGL blazars from the Fermi-LAT fourth source catalogue, looking for with counterparts in the Australian SKA Pathfinde…
Constraints on minimally and conformally coupled ultralight dark matter with the EPTA
Clemente Smarra
Millisecond pulsars are extremely stable natural timekeepers. Pulsar Timing Array experiments, tracking subtle changes in the pulsars' rotation periods, can shed light on the prese…
Cosmology and nuclear-physics implications of a subsolar gravitational-wave event
Francesco Crescimbeni, Gabriele Franciolini, Paolo Pani +1
Detecting a compact subsolar object would have profound implications in physics, the reach of which depends on the nature of the object. Here we explore such consequences for a put…
HERMES: Gamma Ray Burst and Gravitational Wave counterpart hunter
G. Ghirlanda, L. Nava, O. Salafia +67
Gamma Ray Bursts (GRBs) bridge relativistic astrophysics and multi-messenger astronomy. Space-based gamma/X-ray wide field detectors have proven essential to detect and localize th…
Constraints on conformal ultralight dark matter couplings from the European Pulsar Timing Array
Clemente Smarra, Adrien Kuntz, Enrico Barausse +15
Millisecond pulsars are extremely precise celestial clocks: as they rotate, the beamed radio waves emitted along the axis of their magnetic field can be detected with radio telesco…
The second data release from the European Pulsar Timing Array: VI. Challenging the ultralight dark matter paradigm
Clemente Smarra, Boris Goncharov, Enrico Barausse +68
Pulsar Timing Array experiments probe the presence of possible scalar or pseudoscalar ultralight dark matter particles through decade-long timing of an ensemble of galactic millise…
The self-confinement of electrons and positrons from dark matter
Marco Regis, Michael Korsmeier, Gianni Bernardi +3
Radiative emissions from electrons and positrons generated by dark matter (DM) annihilation or decay are one of the most investigated signals in indirect searches of WIMPs. Ideal t…
Catching a nova X-ray/UV flash in the visible? Early spectroscopy of the extremely slow Nova Velorum 2022 (Gaia22alz)
E. Aydi, L. Chomiuk, J. Mikołajewska +22
We present early spectral observations of the very slow Galactic nova Gaia22alz, over its gradual rise to peak brightness that lasted 180 days. During the first 50 days, when the n…
Localisation of gamma-ray bursts from the combined SpIRIT+HERMES-TP/SP nano-satellite constellation
Matt Thomas, Michele Trenti, Riccardo Campana +24
Multi-messenger observations of the transient sky to detect cosmic explosions and counterparts of gravitational wave mergers critically rely on orbiting wide-FoV telescopes to cove…
Optical circular polarization induced by axionlike particles in blazars
Run-Min Yao, Xiao-Jun Bi, Jin-Wei Wang +1
We propose that the interaction between the axionlike particles (ALPs) and photons can be a possible origin of optical circular polarization (CP) in blazars. Given that there is no…
The strongest cool core in REXCESS: Missing X-ray cavities in RXC J2014.8-2430
Tony Mroczkowski, Megan Donahue, Joshiwa van Marrewijk +8
We present a multiwavelength study of RXC J2014.8-2430, the most extreme cool-core cluster in the Representative Cluster Structure Survey (REXCESS), using X-…
Core-collapse Supernovae in the Dark Energy Survey: Luminosity Functions and Host Galaxy Demographics
M. Grayling, C. P. Gutiérrez, M. Sullivan +73
We present the luminosity functions and host galaxy properties of the Dark Energy Survey (DES) core-collapse supernova (CCSN) sample, consisting of 69 Type II and 50 Type Ibc spect…
