UGC 10043 in Depth: Dissecting the Polar Bulge and Subtle LSB Features
Galaxies with polar structures -- of which polar-ring galaxies (PRGs) are a prominent subclass -- contain components that are kinematically decoupled and highly inclined relative to the host galaxy's major axis. Modern deep optical surveys provide a powerful means of detecting low surface brightness (LSB) features around galaxies, offering critical insights into the formation and evolution of galaxies with polar structures. UGC 10043 is an edge-on galaxy notable for its prominent bulge, which e…

Morphology and stellar populations of a candidate ultra-diffuse galaxy in early Euclid and Rubin imaging
We present multi-wavelength imaging and analysis of a low surface brightness (LSB) dwarf galaxy in the Extended Chandra Deep Field South (ECDFS), SMDG0333094-280938, with particular emphasis on data from the Euclid space telescope and from the Vera C.\ Rubin Observatory. The galaxy is clumpy and blue, and appears to host globular clusters (GCs), suggesting a distance of ~50-60 Mpc which would make the dwarf an ultra-diffuse galaxy (UDG). We carry out spectral energy distribution (SED) fitting f…

Black hole surrounded by perfect fluid dark matter with a background Kalb-Ramond field
With an intent to explore the interplay between the Lorentz symmetry breaking (LSB) and the presence of dark matter (DM), we obtain a static and spherically symmetric black hole (BH) solution in the background of nonminimally coupled Kalb-Ramond (KR) field surrounded by perfect fluid dark matter (PFDM). The KR field is frozen to a non-zero vacuum expectation value (VEV) that breaks the particle Lorentz symmetry spontaneously. We explore scalar invariants, Ricci Scalar, Ricci squared, and Kretsc…

Correcting for the effects of the point spread function in intra-halo light measurements and application to deep Hyper Suprime-Cam data
The intra-halo light (IHL) is the diffuse stellar component that surrounds galaxies, groups, and clusters. Its formation is intimately linked to the hierarchical assembly of the system, making it a key tracer of galaxy evolution. However, the low surface brightness (LSB) of the IHL makes it challenging to detect and also to distinguish from the point spread function (PSF) effect of the telescope. In this paper, we present two independent techniques that, when combined, provide a statistically r…

Global monopole in a Ricci-coupled Kalb-Ramond bumblebee gravity
In this paper, we investigate black hole solutions in Einstein-Kalb-Ramond (EKR) bumblebee gravity sourced by a global monopole characterized by the charge $η$. This modified theory of gravity possesses the notable feature of incorporating local Lorentz symmetry breaking (LSB) via a spontaneous symmetry-breaking mechanism. We solve the field equations for a static and spherically symmetric metric with the Kalb-Ramond (KR) field fixed at its VEV, thereby obtaining new black hole solutions. Thes…
