Real Lagrangians in Calabi-Yau Threefolds

Hülya Argüz, Thomas Prince

We compute the mod cohomology groups of real Lagrangians in Calabi-Yau threefolds using well-behaved torus fibrations constructed by Gross. To do this we study a long exact seq…

Circumstellar interaction in the extreme white dwarf merger remnant ZTF\,J1901+1458: A new class of white dwarf merger remnants with X-ray emission

Aayush Desai, Ilaria Caiazzo, Stephane Vennes +31

Double degenerate white dwarf (WD) mergers can exhibit extreme magnetic fields exceeding G and rapid rotation, but their spectral-energy distributions and high-energy emis…

Deep learning to improve the discovery of near-Earth asteroids in the Zwicky Transient Facility

Belén Yu Irureta-Goyena, George Helou, Jean-Paul Kneib +7

We present a novel pipeline that uses a convolutional neural network (CNN) to improve the detection capability of near-Earth asteroids (NEAs) in the context of planetary defense. O…

Polygons of Finite Mutation Type

Thomas Prince

We classify Fano polygons with finite mutation class. This classification exploits a correspondence between Fano polygons and cluster algebras, refining the notion of singularity c…

Smoothing Toric Fano Surfaces Using the Gross-Siebert Algorithm

Thomas Prince

A toric del Pezzo surface with cyclic quotient singularities determines and is determined by a Fano polygon . We construct an affine manifold with singularities that parti…

A half-ring of ionized circumstellar material trapped in the magnetosphere of a white dwarf merger remnant

Andrei A. Cristea, Ilaria Caiazzo, Tim Cunningham +31

Many white dwarfs are observed in compact double white dwarf binaries and, through the emission of gravitational waves, a large fraction are destined to merge. The merger remnants…

The Birational Geometry of Ceva's Theorem

Thomas Prince

In this article we study Ceva's theorem and its higher-dimensional extensions from the perspective of algebraic and projective geometry. First, we situate the theorem within the st…

On the cohomology groups of real Lagrangians in Calabi-Yau threefolds

Hülya Argüz, Thomas Prince

The quintic threefold is the most studied Calabi-Yau -fold in the mathematics literature. In this paper, using Čech-to-derived spectral sequences, we investigate the mod $2…

The IPAC Image Subtraction and Discovery Pipeline for the intermediate Palomar Transient Factory

Frank Masci, Russ Laher, Umaa Rebbapragada +17

We describe the near real-time transient-source discovery engine for the intermediate Palomar Transient Factory (iPTF), currently in operations at the Infrared Processing and Analy…

Mutation equivalence of toric Landau-Ginzburg models

Thomas Prince

Given a Fano complete intersection defined by sections of a collection nef line bundles on a Fano toric manifold , a construction of Givental/Hori-Vafa provide…

Mirror Symmetry and the Classification of Orbifold del Pezzo Surfaces

Mohammad Akhtar, Tom Coates, Alessio Corti +6

We state a number of conjectures that together allow one to classify a broad class of del Pezzo surfaces with cyclic quotient singularities using mirror symmetry. We prove our conj…

The Physics of Mass Transfer in Substellar and Low-Mass Binaries

Samuel Whitebook, Jim Fuller, Kevin Burdge +3

Several dozen binary ultracool and brown dwarf systems have been identified to date. These systems represent valuable probes of star and planet formation at the lowest mass scales.…

Cracked Polytopes and Fano Toric Complete Intersections

Thomas Prince

We introduce the notion of cracked polytope, and - making use of joint work with Coates and Kasprzyk - construct the associated toric variety as a subvariety of a non-singular…

Smoothing Calabi-Yau toric hypersurfaces using the Gross-Siebert algorithm

Thomas Prince

We explain how to form a novel dataset of simply connected Calabi-Yau threefolds via the Gross-Siebert algorithm. We expect these to degenerate to Calabi-Yau toric hypersurfaces wi…

A Note on Schoen's Calabi--Yau Threefolds

Hülya Argüz, Thomas Prince

We study the topology of a real Lagrangian in Schoen's Calabi--Yau threefold and compute its mod cohomology using two methods; first via a concrete Mayer--Vietoris calculat…

A Mass Transferring Brown Dwarf Binary on a 57 Minute Orbit

Samuel Whitebook, Antonio C. Rodriguez, Kevin Burdge +9

Mass transfer in stellar binaries has been well studied in most stellar mass ranges, with the notable exception of ultracool stars and substellar brown dwarfs. We report the discov…

Four-dimensional Fano toric complete intersections

Tom Coates, Alexander Kasprzyk, Thomas Prince

We find at least 527 new four-dimensional Fano manifolds, each of which is a complete intersection in a smooth toric Fano manifold.

The Tropical Superpotential For

Thomas Prince

We present an extended worked example of the computation of the tropical superpotential considered by Carl--Pumperla--Siebert. In particular we consider an affine manifold associat…

Del Pezzo surfaces with a single 1/k(1,1) singularity

Daniel Cavey, Thomas Prince

Inspired by the recent progress by Coates-Corti-Kasprzyk et al. on Mirror Symmetry for del Pezzo surfaces, we show that for any positive integer k the deformation families of del P…

Laurent Inversion

Tom Coates, Alexander Kasprzyk, Thomas Prince

We describe a practical and effective method for reconstructing the deformation class of a Fano manifold X from a Laurent polynomial f that corresponds to X under Mirror Symmetry.…

From Cracked Polytopes to Fano Threefolds

Thomas Prince

We construct Fano threefolds with very ample anti-canonical bundle and Picard rank greater than one from cracked polytopes - polytopes whose intersection with a complete fan forms…

Laurent Inversion

Tom Coates, Alexander Kasprzyk, Thomas Prince

There are well-understood methods, going back to Givental and Hori--Vafa, that to a Fano toric complete intersection X associate a Laurent polynomial f that corresponds to X under…

Minimality and mutation-equivalence of polygons

Alexander Kasprzyk, Benjamin Nill, Thomas Prince

We introduce a concept of minimality for Fano polygons. We show that, up to mutation, there are only finitely many Fano polygons with given singularity content, and give an algorit…
