Modeling and Subtracting Diffuse Cluster Light in JWST Images: A Relation between the Spatial Distribution of Globular Clusters, Dwarf Galaxies, and Intracluster Light in the Lensing Cluster SMACS 0723

The Astrophysical Journal
We present a methodology for modeling and removing light from cluster galaxies and intracluster light (ICL) from James Webb Space Telescope images of gravitational lensing clusters.

The NIKA2 Sunyaev-Zeldovich Large Program [PDF]

EPJ Web of Conferences
The NIKA2 camera operating at the IRAM 30-m telescope excels in high-angular resolution mapping of the thermal Sunyaev-Zel’dovich effect towards galaxy clusters at intermediate and high-redshift. As part of the NIKA2 guaranteed-time, the SZ Large Program

Galaxy clustering and its dependencies at high redshift

, 2021
Studies of the galaxy clustering at low and intermediate redshifts show that the relation between the luminous structure and underlying dark matter distribution is not only biased but also dependent on properties of galaxies. To understand the origin of this separation the studies need to be conducted on spectroscopic data at higher redshift. With this

Searching the Non‐Accreting White Dwarf Population in eROSITA Data

Astronomische Nachrichten, Volume 346, Issue 1, January 2025.
ABSTRACT eROSITA is the soft X‐ray instrument aboard the Spectrum Roentgen Gamma (SRG) satellite that is most sensitive in the energy range between 0.2 and 2.3 keV. Between December 2019 and December 2021, eROSITA completed four all‐sky surveys, producing all‐sky X‐ray source lists and sky maps of unprecedented depth.

JADES: A Prominent Galaxy Overdensity Candidate within the First 500 Myr

The Astrophysical Journal
We report a galaxy overdensity candidate at z  ≈ 10.5 in the JWST Advanced Deep Extragalactic Survey. This overdensity contains 18 galaxies with consistent photometric redshifts within 8 comoving Mpc in projection.

Probing extreme black‐hole outflows on short timescales via high spectral‐resolution x‐ray imagers

Astronomische Nachrichten, Volume 345, Issue 6-7, July-August 2024.
Abstract We investigate outflows and the physics of super‐Eddington versus sub‐Eddington regimes in black hole systems. Our focus is on prospective science using next‐generation high‐resolution soft x‐ray instruments. We highlight the properties of black hole ultraluminous x‐ray source (ULX) systems in particular. Owing to scale invariance in accreting

The clustering of dark matter, haloes & galaxies [PDF]

, 2008
In this thesis I study the spatial distribution of galaxies, haloes and dark matter particles using a suite of state-of-art cosmological N-body simulations of the growth structure in the Universe.

Clustering analysis of high-redshift luminous red galaxies in Stripe 82 [PDF]

Monthly Notices of the Royal Astronomical Society, 2012
We present a clustering analysis of Luminous Red Galaxies in SDSS Stripe 82. We study the angular 2-point correlation function, of 130,000 LRG candidates via colour-cut selections in izK with the K band coverage coming from UKIDSS LAS. We have used the cross-correlation technique of Newman (2008) to establish the LRG redshift distribution.

Flexible, Photonic Films of Surfactant‐Functionalized Cellulose Nanocrystals for Pressure and Humidity Sensing

Small Structures, Volume 5, Issue 7, July 2024.
Cellulose nanocrystals are abundant, biodegradable nanoparticles that can self‐assemble into a helical stacking that exhibits structural color. By adding a single surfactant, cellulose nanocrystals can be made compatible with apolar solvents, which are widely used for industrial coatings.
