Morse Theory for the Space of Higgs Bundles
, 2008 Here we prove the necessary analytic results to construct a Morse theory for the Yang-Mills-Higgs functional on the space of Higgs bundles over a compact Riemann surface.

Genomic organization of the rDNA cistron of the teleost fish Cyprinus carpio
Biological Research, 2003 The seasonal adaptation of the teleost Cyprinus carpio to the cyclical changes of its habitat demands physiological compensatory responses. The process involves profound nucleolar adjustments and remarkable changes in rRNA synthesis, which affects ...

Streams, Shells, and Substructures in the Accretion-built Stellar Halo of NGC 300
The Astrophysical Journal LettersWe present deep optical observations of the stellar halo of NGC 300, an LMC-mass galaxy, acquired with the DEEP subcomponent of the DECam Local Volume Exploration survey using the 4 m Blanco Telescope.

Numerical test of Polyakov loop models in high temperature SU(2)
, 2004 We study the compatibility of effective mean-field models of the Polyakov loop for the deconfined phase of SU(N) pure gauge theories with lattice data obtained for the case of SU(2), in the temperature range T_c - 4.8 T_c.Comment: Poster presented at ...

A General Framework for Recursive Decompositions of Unitary Quantum Evolutions
, 2008 Decompositions of the unitary group U(n) are useful tools in quantum information theory as they allow one to decompose unitary evolutions into local evolutions and evolutions causing entanglement.

Experimental approaches for 100 TeV gamma-ray astronomy
, 2006 The high energy end of gamma-ray source spectra might provide important clues regarding the nature of the processes involved in gamma-ray emission. Several galactic sources with hard emission spectra extending up to more than 30TeV have already been ...

Quartz Clouds in the Dayside Atmosphere of the Quintessential Hot Jupiter HD 189733 b
The Astrophysical Journal LettersRecent mid-infrared observations with JWST's Mid-Infrared Instrument Low Resolution Spectrometer (MIRI LRS) have resulted in the first direct detections of absorption features from silicate clouds in the transmission spectra of two transiting exoplanets,

Two-dimensional Radiation-hydrodynamic Simulations of Luminous Red Novae
The Astrophysical Journal LettersLuminous red novae (LRNe) are transients associated with mass ejection during stellar mergers and common envelope evolution (CEE). LRNe have the potential to illuminate the poorly understood phases of binary evolution leading up to the CEE, during the ...
