Disturbed, diffuse, or just missing? A global study of the H I content of Hickson compact groups
(EDP Sciences, 2023)
Context. Hickson compact groups (HCGs) are dense configurations of four to ten galaxies, whose H I morphology appears to follow an evolutionary sequence of three phases, with gas initially confined to galaxies, then ...
Influence of Synthesis Method on Structural, Morphological, Magnetic, and Antimicrobial Properties of Fe-Ag Nanoparticles
(Journal of Inorganic and Organometallic Polymers and Materials, 2023)
This contribution reports on the development of two versatile and efficient methods, namely the green and gamma radiolysis for Fe-Ag nanoparticles (NPs) synthesis, characterization, and further their growth inhibition ...
Interferometric H I intensity mapping: perturbation theory predictions and foreground removal effects
(Oxford University Press, 2023)
We provide perturbation theory predictions for the H I intensity mapping power spectrum multipoles using the Effective Field
Theory of Large Scale Structure, which should allow us to exploit mildly non-linear scales. ...
A search for variable subdwarf B stars in TESS Full Frame Images III. An update on variable targets in both ecliptic hemispheres – contamination analysis and new sdB pulsators
(Oxford University Press, 2023)
We present an update on the variable star survey performed on the TESS 30 min Full Frame
Image (FFI) data reported by our first two papers in this series. This update includes a
contamination analysis in order to identify ...
The LOFAR Tied-Array All-Sky Survey: Timing of 35 radio pulsars and an overview of the properties of the LOFAR pulsar discoveries
(Astronomy& Astrophysics, 2023)
The LOFAR Tied-Array All-Sky Survey (LOTAAS) is the most sensitive untargeted radio pulsar survey performed at low radio frequencies (119−151 MHz) to date and has discovered 76 new radio pulsars, including the 23.5-s pulsar ...
Galaxy and Mass Assembly (GAMA): Mid-infrared properties as tracers of galaxy environment
(EDP Sciences, 2023)
We investigate how different mid-infrared (mid-IR) properties of galaxies are correlated with the environment in which the
galaxies are located. For this purpose, we first study the dependence of galaxy clustering on the ...
Probing Cosmology beyond ΛCDM using the SKA
(Indian Academy of Sciences, 2023)
The cosmological principle states that the Universe is statistically homogeneous and isotropic at
large distance scales. Currently, there exist many observations which indicate a departure from this principle.
It has ...
Ceers key paper. I. An early look into the first 500myr of galaxy formation with jwst
(American Astronomical Society, 2023)
We present an investigation into the first 500 Myr of galaxy evolution from the Cosmic Evolution Early Release
Science (CEERS) survey. CEERS, one of 13 JWST ERS programs, targets galaxy formation from z ∼ 0.5 to >10
using ...
Isoscalar giant monopole strength in 58Ni, 90Zr, 120Sn and 208Pb
(American Physical Society, 2023)
Inelastic α-particle scattering at energies of a few hundred MeV and very-forward
scattering angles including 0° has been established as a tool for the study of the isoscalar giant
monopole (IS0) strength distributions ...
PSRJ1910–5959A: A rare gravitational laboratory for testing white dwarf models
(EDP Sciences, 2023)
Context. PSR J1910-5959A is a binary millisecond pulsar in a 0.837 day circular orbit around a helium white dwarf (HeWD) companion. The position of this pulsar is 6.3 arcmin (∼74 core radii) away from the optical centre ...
