XRISM/Resolve reveals the complex iron structure of NGC 7213: Evidence for radial stratification between inner disk and broad-line region
E. Kammoun, T. Kawamuro, K. Murakami +48
We present the first high-resolution X-ray spectrum of NGC 7213 obtained with XRISM/Resolve, supported by simultaneous XMM-Newton, NuSTAR, and SOAR optical data. The XRISM spectrum…
Spatial resolution studies with the BabyIAXO Micromegas prototype
A. Quintana, J. Castel, S. Cebrián +20
The spatial resolution of the Micromegas prototype developed for the BabyIAXO experiment was evaluated using a low-energy X-ray beam at the SOLEIL synchrotron facility. BabyIAXO, c…
The Structure of the Relativistic Fe Line in GX 340+0 as Viewed with XRISM/Resolve, NICER, and NuSTAR
R. M. Ludlam, R. Ballhausen, P. Chakraborty +13
We present a 152 ks XRISM/Resolve observation of the persistently accreting Z source GX 340+0. Simultaneous observations also occurred with NuSTAR and NICER for 22.47 ks and 2.7 ks…
On the nature of the X-ray binary transient MAXI J1834-021: clues from its first observed outburst
A. Manca, A. Marino, A. Borghese +14
MAXI J1834-021 is a new X-ray transient that was discovered in February 2023. We analysed the spectral and timing properties of MAXI J1834-021 using NICER, NuStar and Swift data co…
Dirac bracket and Nambu structures
J. Antonio García, Rafael Cruz-Alvarez
A relation between the Dirac bracket (DB) and Nambu bracket (NB) is presented. The Nambu bracket can be related with Dirac bracket if we can write the DB as a generalized Poisson s…
Constraints on the energy spectrum of the diffuse cosmic neutrino flux from the ANTARES neutrino telescope
ANTARES Collaboration, A. Albert, S. Alves +139
High-significance evidences of the existence of a high-energy diffuse flux of cosmic neutrinos have emerged in the last decade from several observations by the IceCube Collaboratio…
Argon X-ray absorption in the local ISM
E. Gatuzz, T. W. Gorczyca, M. F. Hasoglu +2
We present the first comprehensive analysis of the argon K-edge absorption region (3.1-4.2 Å) using high-resolution HETGS {\it Chandra} spectra of 33 low-mas X-ray binaries. Utiliz…
Recovery of the X-ray polarisation of Swift J1727.81613 after the soft-to-hard spectral transition
J. Podgorný, J. Svoboda, M. Dovčiak +34
We report on the detection of X-ray polarisation in the black-hole X-ray binary Swift J1727.81613 during its dim hard spectral state by the Imaging X-ray Polarimetry Explorer (I…
Background discrimination with a Micromegas detector prototype and veto system for BabyIAXO
K. Altenmüller, J. F. Castel, S. Cebrián +22
In this paper we present measurements performed with a Micromegas X-ray detector setup. The detector is a prototype in the context of the BabyIAXO helioscope, which is under constr…
Elemental abundances in the diffuse ISM from joint FUV and X-ray spectroscopy: iron, oxygen, carbon and sulfur
I. Psaradaki, L. Corrales, J. Werk +10
In this study, we investigate interstellar absorption lines along the line of sight toward the galactic low-mass X-ray binary Cygnus X-2. We combine absorption line data obtained f…
SRG/eROSITA 3D mapping of the ISM using X-ray absorption spectroscopy
E. Gatuzz, J. Wilms, A. Zainab +6
We present a detailed study of the hydrogen density distribution in the local interstellar medium (ISM) using the X-ray absorption technique. Hydrogen column densities were precise…
Radius Constraints from Reflection Modeling of Cygnus X-2 with NuSTAR and NICER
R. M. Ludlam, E. M. Cackett, J. A. García +8
We present a spectral analysis of NuSTAR and NICER observations of the luminous, persistently accreting neutron star (NS) low-mass X-ray binary Cygnus X-2. The data were divided in…
Noether Identities, -functions and symmetries in DFT
J. Antonio García, R. Abraham Sánchez-Isidro
Given the functions of the closed string sigma model up to one loop in , the effective action implement the condition to preserve conformal symmetry at quantum level.…
