Title: Revisiting Tidal Deformations in Black Holes
Abstract: Recent advancements suggest that tidal forces, traditionally expected to vanish in extremal black holes, may play a more fundamental role than previously thought. In this talk, we review the tidal deformations of black holes, focusing on the role of Love numbers in characterizing these deformations, and explore the unique properties of tidal interactions in extremal black holes.

Title: What if String Theory has a de Sitter Excited State? Abstract: In this talk I’ll discuss and provide reasons why de Sitter space should be viewed as an excited state in the low energy effective action of string theory. I’ll also show that the alternative, i.e a vacuum state solution, may not be compatible with Wilsonian effective action or the exact renormalization group principle.

Title: Towards String Perturbation Theory in Ramond Backgrounds Abstract: We demonstrate how recent developments in string field theory provide a framework to systematically study type II flux compactifications with non-trivial Ramond-Ramond profiles. We present an explicit example where physical observables can be computed order by order in a small parameter which can be effectively viewed as ...

Title: Cosmology and Astrophysics with the Secondary Anisotropies of the Cosmic Microwave Background from South Pole Telescope and Future Surveys Abstract: Observations of cosmic microwave background (CMB) have played critical role in establishing the standard cosmological paradigm, the six-parameter Lambda cold dark matter model. In particular, secondary anisotropies of the CMB are remarkable ...

Title: Magnetism and Morphology in the Interstellar Medium Abstract: The interstellar medium (ISM) is a turbulent, multi-phase, magnetic environment. Magnetic fields thread our Milky Way Galaxy, influencing interstellar physics from cosmic ray propagation to star formation. The magnetic interstellar medium is also a formidable foreground for experimental cosmology, particularly for the quest to...

Title: The Origin of the Heaviest Elements Abstract: Understanding the origin of the elements remains one of the major challenges of modern astrophysics. I will introduce some of the big, open questions in the field and present several major advances from recent years. These advances include measuring the most complete heavy element chemical inventory beyond the Solar System, the first detectio...

Title: Galaxies from Here to Eternity: Too Big Too Soon? Abstract: The launch of JWST has led to the discovery of massive galaxies in the high redshift universe. These galaxies appear to have grown too big too fast for the standard cold dark matter structure formation paradigm, posing a substantial challenge to an important aspect of cosmology. The early appearance of massive galaxies was never...

Title: The Structure and Dynamics of the Interstellar Medium of Galaxies in the Early Universe Abstract: We are reaching a critical moment where sub-arcsec observations are key to disentangle the physical mechanisms that shaped young galaxies at z ~ 5. In my talk, I will explore the morphology and kinematics of the cold gas, star-forming, and stellar components of CRISTAL-05, a massive star-for...

Title: Decoding the Cosmic Evolution of Galaxies Through Their Multiphase Interstellar Medium Abstract: The prominent peak in the history of star formation and black hole accretion ~10 billion years ago, an epoch known as cosmic noon, suggests strong evolution in the conditions under which stars and supermassive black holes grow in galaxies over time. These key processes in galaxy growth leave ...

Title: Understanding the Regions Around Supermassive Black Holes at the Centers of Galaxies Using Small Robotic Observatories Abstract: Active Galactic Nuclei (AGN) occur in the centers of galaxies where a supermassive black hole is actively accreting material via an accretion disk. Reverberation mapping is a technique used to estimate the size of the accretion disk by measuring time delays bet...

Title: Constraining the SMEFT with Right-Handed Neutrinos at FCC-ee Abstract: The existence of right-handed neutrinos (RHNs), or heavy neutral leptons (HNLs), is strongly motivated by the observation of small but finite neutrino masses and mixings. In this talk, I will present the extended the Standard Model particle content with a pair of gauge-singlet fermions, which can be Dirac or Majorana ...

Title: Dirac Neutrinos and Parity Solution to the Strong CP Problem in SU(5)_L x SU(5)_R Abstract: We develop a grand unified theory of matter and forces based on the gauge symmetry SU(5)L × SU(5)R with parity interchanging the two factor groups. The main motivation for such a construction is to realize a minimal GUT embedding of left-right symmetric models that provide a parity solution to the...

Title: Prospects of Natural Anomaly Mediated SUSY Breaking at HL-LHC Abstract: The minimal anomaly mediated supersymmetry breaking (AMSB) models are currently in conflict with constraints from naturalness, Higgs mass and sparticle mass limits from LHC as well as from dark matter searches on the wino-like neutralino which serves as the lightest SUSY particle (LSP). These conflicts may be avoided...

Title: Non-Standard Interactions of Supernova Neutrinos and Mass Ordering Ambiguity at DUNE Abstract: We show that non-standard neutrino interactions (NSI) can notably modify the pattern of resonant flavor conversion of neutrinos within supernovae and significantly impact the neutronization burst signal in forthcoming experiments such as the Deep Underground Neutrino Experiment (DUNE). The pres...

    Strong points. If dark matter wins in the end they'll have some explaining to do, as to why dark matter always places itself in such a way that its effects sum up to the Milgrom formula.

    Good for you, you made a clear connection between Ginzbug-Landau model and Higgs Bozon. Although, Ginzbug himself mentioned that he and Landau wrote only one paper together, and that is where Ginzbug was close to discovering Cooper pairs.

    Can you please explain what these benchmark models signify? Meaning, what does the space dependent, space independent and hybrid gamma model depict? Another question being, if the life time of a DM particle is >> the age of the Universe, then why are we talking about DM decay in the first place?
