 ====== February 2026 ======
+Here is a curated list of relevant ''astro-ph'' submissions from February 2026 that align with your research interests in 21-cm cosmology, the Epoch of Reionization (EoR), foreground mitigation, and machine learning. Each paper is mapped directly to the relevant CASSA projects.
+===== 1. Nearest Neighbour-Based Statistics for 21cm-Galaxy Cross-Correlations in the Epoch of Reionization =====
+Authors: Anirban Chakraborty, Kwanit Gangopadhyay, Arka Banerjee, Tirthankar Roy Choudhury
+arXiv Link: [[https://arxiv.org/abs/2602.15803|arXiv:2602.15803]]
+Summary: To overcome severe contamination from astrophysical foregrounds and instrumental noise, this paper investigates k-nearest-neighbour cumulative distribution functions as an alternative to two-point statistics. The method shows promise in extracting maximal information from 21cm-galaxy cross-correlations even under aggressive foreground filtering.
+Relevant CASSA Projects: RiFInE, PrimaBERA, MiMiC
+===== 2. The Epoch of Reionization 21 cm Bispectrum at z=8.2 from MWA data II: Smooth Component Filtering =====
+Authors: Sukhdeep Singh Gill, Khandakar Md Asif Elahi, Somnath Bharadwaj, Shiv K. Sethi, Akash Kumar Patwa
+arXiv Link: [[https://arxiv.org/abs/2602.17304|arXiv:2602.17304]]
+Summary: This paper demonstrates the mitigation of dominant astrophysical foregrounds using Smooth Component Filtering (SCF) to estimate the 21 cm bispectrum from Murchison Widefield Array (MWA) observations, establishing new limits on the EoR signal.
+Relevant CASSA Projects: RiFInE, PrimaBERA, START
+===== 3. Establishing a relationship between the cosmological 21 cm power spectrum and interferometric closure phases =====
+Authors: Pascal M. Keller, Bojan Nikolic, Nithyanandan Thyagarajan
+arXiv Link: [[https://arxiv.org/abs/2602.04965|arXiv:2602.04965]]
+Summary: Aims to establish a mathematical relationship between calibration-independent closure phases and the cosmological 21 cm power spectrum. It provides a robust technique to sidestep calibration inaccuracies that typically compromise the spectral fidelity of the smooth foreground continuum.
+Relevant CASSA Projects: CHronOS, START
+===== 4. Interpreting the HI 21-cm cosmology maps through Largest Cluster Statistics III: Impact of the lightcone effect =====
+Authors: Hemanth Potluri, Manas Mohit Dosibhatla, Leon Noble, Chandra Shekhar Murmu, Suman Majumdar, Samit Kumar Pal, Saswata Dasgupta, Satadru Bag, Abhirup Datta
+arXiv Link: [[https://arxiv.org/abs/2602.16651|arXiv:2602.16651]]
+Summary: By analyzing 21-cm brightness temperature fields in the image domain to retain non-Gaussian characteristics, this work tracks the coalescence of ionized regions using the Largest Cluster Statistic (LCS) to infer the topology of the EoR along a lightcone.
+Relevant CASSA Projects: PrimaBERA
+===== 5. Seeing Wiggles without Seeing Wiggles: BAO Recovery in 21 cm Intensity Mapping with Deep Learning =====
+Authors: Kaifeng Yu, Xin Wang
+arXiv Link: [[https://arxiv.org/abs/2602.03313|arXiv:2602.03313]]
+Summary: Employs a deep learning approach to recover large-scale baryon acoustic oscillations (BAO) lost to foreground avoidance strategies. It attempts to restore missing large-scale modes by exploiting physical non-linear mode coupling from short-wavelength data.
+Relevant CASSA Projects: MiMiC, RiFInE
+===== 6. The Signature of Strong High-Redshift Radio Backgrounds on the Cosmic Dawn 21-cm Bispectrum =====
+Authors: Sudipta Sikder, Rajesh Mondal, Rennan Barkana, Anastasia Fialkov
+arXiv Link: [[https://arxiv.org/abs/2602.13445|arXiv:2602.13445]]
+Summary: Investigates how an inhomogeneous excess galactic radio background and line-of-sight fluctuations from early galaxies introduce significant non-Gaussianity into the Cosmic Dawn 21-cm signal, which can be measured using the squeezed-limit bispectrum.
+Relevant CASSA Projects: PrimaBERA, CHronOS
+===== 7. Reionization Bubbles from Real-Space Cross Correlations of Line Intensity Maps =====
+Authors: Emilie Thélie, Sarah Libanore, Yonatan Sklansky, Julian B. Muñoz, Ely D. Kovetz
+arXiv Link: [[https://arxiv.org/abs/2602.12277|arXiv:2602.12277]]
+Summary: Because directly mapping ionized bubbles is challenging due to high redshifts and intense foregrounds, this paper reconstructs the ionized-bubble size distribution during the EoR through the real-space cross-correlation of 21-cm and star-forming line-intensity maps.
