Dynamically derived morphology from the recurrence patterns of close binary stars using Kepler data
In this work, we propose a novel method to classify close binary stars, derived from the dynamical structure inherent in their light curves. We apply the technique to light curves of binaries from the revised Kepler Eclipsing binary catalog, selecting close binaries which have the standard morphology parameter, $c$, $\gt 0.5$ corresponding to semi-detached, over-contact and ellipsoidal systems. Using the method of time delay embedding, we recreate the non-linear dynamics underlying the data and…

Candidate red supergiants from Gaia DR3 BPRP spectra: From the Perseus to the Scutum-Crux spiral arms
Context. Our position within the Galactic plane and the dust obscuration make it challenging to retrieve a true picture of the Milky Way's morphology. While the Milky Way has been recognized as a barred spiral galaxy since the 1960s, there is still uncertainty about the exact number of spiral arms it contains. Currently, our understanding of the Galaxy is evolving thanks to the unprecedented detail provided by Gaia's parallactic distances. Aims. To shed light on the spatial distribution of red …

Grasp2Grasp: Vision-Based Dexterous Grasp Translation via Schrödinger Bridges
We propose a new approach to vision-based dexterous grasp translation, which aims to transfer grasp intent across robotic hands with differing morphologies. Given a visual observation of a source hand grasping an object, our goal is to synthesize a functionally equivalent grasp for a target hand without requiring paired demonstrations or hand-specific simulations. We frame this problem as a stochastic transport between grasp distributions using the Schrödinger Bridge formalism. Our method lear…

Detecting secondary-phase in bainite microstructure through deep-learning based single-shot approach
Relating properties and processing conditions to multiphase microstructures begins with identifying the constituent phases. In bainite, distinguishing the secondary phases is an arduous task, owing to their intricate morphology. In this work, deep-learning techniques deployed as object-detection algorithms are extended to realise martensite-austenite (MA) islands in bainite microstructures, which noticeably affect their mechanical properties. Having explored different techniques, an extensively…

Magnetic evolution of complex solar active regions
Aims. This study investigates the magnetic evolution of solar active regions (ARs), with a particular focus on understanding how the magnetic morphology of simple and complex ARs changes throughout their lifetime. Methods. To analyse the magnetic evolution of ARs, we developed a Magnetic Evolution Method (MEM) that segments each region's lifetime into three phases: growth, main, and recovery. The method was applied to ARs observed between January 1996 and December 2020. Results. We found that c…

Distinguishing Ram Pressure from Tidal Interactions: the Size-Shape Difference (SSD) measure
Context: In dense environments, disk galaxies can be subjected to tidal interactions with other galaxies and/or ram pressure stripping. Some morphological features are clearly associated with one or the other interaction (e.g. tidal bridges vs long one-sided linear gas tails). But, under certain circumstances, both mechanisms can result in morphological features that could be confused, such as lopsided or asymmetric disks and unwinding spiral arms. Aims: Our aim is to develop new measures for…

GAMA 526784: the progenitor of a globular cluster-rich ultra-diffuse galaxy? II. Molecular gas, neutral gas and environment
Aims. We investigate the gas reservoirs, star formation (SF) properties, and environment of the ultra-diffuse galaxy GAMA526784 to understand its formation history, the efficiency of molecular gas conversion into stars, and the possible role of an interacting companion in shaping its morphology. Methods. We analyse low and high-resolution CO observations to constrain the molecular gas content, compare with HI data, and examine the SF efficiency of GAMA526784. The potential influence of a newly …
