Mass Functions and Mass Segregation in Young Starburst Clusters
The Milky Way starburst clusters Arches in the Galactic Center region and NGC 3603 in the Carina spiral arm are studied with the aim to gain deeper insight into the stellar mass distribution in starburst clusters. The dense stellar population in both clusters is resolved in unprecedented detail …

Seyfert and starburst activity in galaxies: Modeling and analysis
… infrared study of galaxies with Seyfert and starburst activity, to constrain the impact of these phenomena on the host galaxy evolution in a local galaxy sample. We developed new tools for stellar population analysis in the infrared, using stellar absorption features. These tools are ideally …

Search for post-starburst (E+A) galaxies in the cluster Abell 3266
… 3266 were analyzed and searched for "E+A" (post-starburst) galaxies, from which we selected two candidate "E+A" galaxies for follow-up high-resolution spectroscopy. The 2 candidate galaxies are confirmed as "E +A" galaxies with high-resolution, slit spectra. The ages of these "E+A" galaxies (i.e. …

The Galactic Starburst Region NGC 3603 : exciting new insights on the formation of high mass stars
… stage. Such premises are given in the Galactic starburst region NGC 3603. Nevertheless, a large observational effort with different telescopes and instruments -- in particular, taking advantage of the high angular resolution and high sensitivity of near and mid IR instruments available at ESO -- …

The Evolution of and Starburst-AGN Connection in Luminous and Ultraluminous Infrared Galaxies and their Link to Globular Cluster Formation
<p>The evolutionary connection between nuclear starbursts and active galactic nuclei (AGN) in luminous infrared galaxies (LIRGs; 1011o<oLIRo< 1012 L) and ultraluminous infrared galaxies (ULIRGs; 1012 < LIR < 1013 L), which result from galaxy interactions and mergers and produce the bulk of their …

A connectomic analysis of the directional selectivity circuit in the mouse retina
… cells, and more recently confirmed in the starburst amacrine cell. Upstream retinal bipolar cells, however, have been shown to lac, indicating that the mechanism that gives rise to DS lies in the inner plexiform layer, where the axons of bipolar cells costratify with amacrine and ganglion …

Development of Patterned Self-Assembled Monolayers Toward the Study of Axonal Differentiation
… in neurons confined to a two-dimensional starburst pattern. We utilize self-assembled monolayer: SAM) chemistry in conjunction with microcontact printing to create stable patterned substrates for cell culture. Photolithography is employed in the fabrication of patterned masters, which are …

Starbursts in extragalactic giant H II regions
… scales, and thus provide ideal labs to analyze starburst phenomena. To get a complete picture of the starburst phenomenon, the critical characteristics we must investigate include star formation history and the interplay between massive stars and the interstellar matter. For starbursts in giant …

Investigation into the unique coordination and spectroscopic properties of lanthanide ions with dipyridylamine and dipicolylamine based ligands.
… Dipyridylamine and dipicolylamine based starburst compounds were synthesized and characterized. X-ray crystallography of ligands and a lithium complex, as well as photophysical properties were investigated and revealed that the compounds that were developed did not sensitize lanthanide …

PREPARATION AND CHARACTERIZATION OF AN ELECTROSPUN GELATIN/DENDRIMER HYBRID NANOFIBER DRESSING
… chronic wounds, degrade the reconstituted ECM. Starburst™ polyamidoamine (PAMAM) dendrimer G3.5, which provides a versatile and structurally controlled architecture to construct nanomedicine, was covalently bonded to the gelatin backbone and electrospun into nanofibers with gelatin, doxycycline …

Characterization of the Role of R7-RGS Proteins in Mammalian Retina and Vision
… In part i), we found that R7BP is expressed in starburst amacrine cells (SAC) and retinal ganglion cells (RGC). R7BP regulates mesopic RGC light responses and glutamatergic wave burst duration in mature and developing retina, respectively. In part ii), we found that R7PB is expressed in the …

Characterising star forming and luminous infrared galaxies with the Southern African Large Telescope (SALT)
… applied to main sequence galaxies. Yet starburst galaxies and Luminous InfraRed Galaxies (LIRGs) have, so far, not been studied as much using the method. LIRGs in the local universe are known to be highly interacting galaxies with strong star formation in obscured environments. Still, …

Searching for Extreme-BCG Clusters at 0.2 < z < 1.3
… with unique characteristics, such as hosting starburst and/or active nuclei, provides an alternative path to tackle the issue of when, and how precisely, AGN feedback impacts clusters. For my Ph.D. thesis, I show that by finding extreme-BCG clusters we can better understand the processes of …

The gas content of luminous compact blue galaxies in the COSMOS field
… galaxies (LCBGs) are a heterogeneous subset of starburst galaxies. Their number density drops quite significantly as we approach lower redshifts. As a set of galaxies that evolve quickly, they make excellent candidates for studying galactic evolution as a whole. In order to understand how …

Mathematical and Deep Learning Methods in High-Energy Physics: From Temporal Variability in M82 ULXs to Spatial Features in Planck Maps
… especially ultraluminous X-ray sources (ULXs) in starburst galaxies, aiming to characterize quasi-periodic variability that reflects the physics of accretion onto compact objects. On the other hand, we develop a machine-learning method to detect and classify sources in wide-field infrared survey …
