Modeling tails of escaping gas in exoplanet atmospheres with Harmonica
Exoplanets that reside close to their host stars, and therefore receive substantial amounts of X-ray and ultraviolet radiation, are prone to suffer from strong atmospheric escape. This can lead to the creation of an envelope of escaping gas along the planet's orbital trajectory, often referred to as a tail. When transiting in front of their host star, these tails can not only produce larger depths in the transit light curves, but also introduce significant asymmetries between ingress and egress…

A $τ$-$DM relation for FRB hosts?
It has been proposed that measurements of scattering times ($τ$) from fast radio bursts (FRB) may be used to infer the FRB host dispersion measure (DM) and its redshift. This approach relies on the existence of a correlation between $τ$ and DM within FRB hosts such as that observed for Galactic pulsars. We assess the measurability of a $τ- $DM$_{\rm host}$ relation through simulated observations of FRBs within the ASKAP/CRAFT survey, taking into account instrumental effects. We show that eve…

Exploring dark matter with quantum-enhanced haloscopes and time projection chambers
This thesis explores experimental and theoretical approaches to dark matter detection, from gas-based detectors to quantum sensors, tackling the challenge of identifying dark matter, which makes up 27% of the Universe's energy. It reviews astrophysical and cosmological evidence, highlights the Standard Model's limitations, and motivates searches for WIMPs, axions, and dark photons through direct, indirect, and collider-based strategies. The experimental work includes the Micromegas-based TREX…

Keanu Reeves and Alex Winter reunite on stage in Broadway’s ‘Waiting for Godot’
It's a classic of theater that continues to be taken on by top actors and still resonates with audiences. “Waiting for Godot” mixes despair and comedy to raise questions about the meaning of life. Now, Keanu Reeves and Alex Winter, two actors who are great friends, are doing their waiting on Broadway. Senior arts correspondent Jeffrey Brown has the story for our arts and culture series, CANVAS.

Role of magnetic shear distribution on the formation of eruptive flux ropes
Erupting flux ropes play crucial role in powering a wide range of solar transients, including flares, jets, and coronal mass ejections. These events are driven by the release of stored magnetic energy, facilitated by the shear in the complex magnetic topologies. However, the mechanisms governing the formation and eruption of flux ropes, particularly the role of magnetic shear distribution in coronal arcades are not fully understood. We employ magnetohydrodynamic simulations incorporating nonadi…

EP250207b is not a collapsar fast X-ray transient. Is it due to a compact object merger?
Fast X-ray Transients (FXTs) are short-lived extra-galactic X-ray sources. Recent progress through multi-wavelength follow-up of Einstein Probe discovered FXTs has shown that several are related to collapsars, which can also produce gamma-ray bursts (GRBs). In this paper we investigate the nature of the FXT EP250207b. The VLT/MUSE spectra of a nearby (15.9 kpc in projection) lenticular galaxy reveal no signs of recent star formation. If this galaxy is indeed the host, EP250207b lies at a redshi…

Little Red Dots and their Progenitors from Direct Collapse Black Holes
The James Webb Space Telescope (JWST) has discovered a new population of objects, the Little Red Dots (LRDs), characterized by V-shaped spectra indicative of strong breaks around the Balmer limit and compact morphology that gave them their name. A popular explanation is that they are a sub-population of active galactic nuclei/supermassive black holes (AGN/SMBHs) predominantly found in the high-redshift Universe ($z\gtrsim3$). Similarly, direct collapse black holes (DCBHs), theorized to form fro…
