Reconstructing Sea Surface Temperature Images: A Masked Autoencoder Approach for Cloud Masking and Reconstruction
We consistently find that at all levels of p there is one or multiple models that reconstruct the images with a mean RMSE of less than 0. 03K, i. e. lower than the estimated sensor error of VIIRS data.
Monte Carlo Physarum Machine: Characteristics of Pattern Formation in Continuous Stochastic Transport Networks
We present Monte Carlo Physarum Machine: a computational model suitable for reconstructing continuous transport networks from sparse 2D and 3D data.
New Evidence for Extended HeII Reionization at z>3.5 from HeII Lyman Alpha and Beta Transmission Spikes
We present new high-resolution (R~14, 000) spectra of the two brightest HeII-transparent quasars in the far-UV (FUV) at z>3. 5, HE2QSJ2311-1417 (z=3. 70) and HE2QSJ1630+0435 (z=3. 81), obtained with the Cosmic Origins Spectrograph (COS) on the Hubble Space Telescope (HST).

Polyphorm: Structural Analysis of Cosmological Datasets via Interactive Physarum Polycephalum Visualization
This paper introduces Polyphorm, an interactive visualization and model fitting tool that provides a novel approach for investigating cosmological datasets.

Fully probabilistic quasar continua predictions near Lyman-α with conditional neural spline flows
Measurement of the red damping wing of neutral hydrogen in quasar spectra provides a probe of the epoch of reionization in the early Universe.
Disentangling the Cosmic Web Towards FRB 190608
Chittidi et al (2020) perform a detailed analysis of the ultraviolet and optical emission of the host galaxy and estimate the host DM contribution to be $110\pm 37$ $pc/cm^3$.

Revealing the Dark Threads of the Cosmic Web
Modern cosmology predicts that matter in our Universe has assembled today into a vast network of filamentary structures colloquially termed the Cosmic Web.
Galactic Gas Flows from Halo to Disk: Tomography and Kinematics at the Milky Way's Disk-Halo Interface
We calculate covering fractions of $f_{CaII}$ = 63%, $f_{NaI}$ = 26%, and $f_{HI}$ = 52%, consistent with a picture of the CGM that includes multi-phase clouds containing small clumps of cool gas within hotter, more diffuse gas.

Fast Radio Burst Tomography of the Unseen Universe
The discovery of Fast Radio Bursts (FRBs) at cosmological distances has opened a powerful window on otherwise unseen matter in the Universe.

IGM-Vis: Analyzing Intergalactic and Circumgalactic Medium Absorption Using Quasar Sightlines in a Cosmic Web Context
We introduce IGM-Vis, a novel astrophysics visualization and data analysis application for investigating galaxies and the gas that surrounds them in context with their larger scale environment, the Cosmic Web.

Deep Learning of Quasar Spectra to Discover and Characterize Damped Lya Systems
Testing on a held-back validation set demonstrates a high incidence of DLAs recovered by the algorithm (97. 4% as DLAs and 99% as an HI absorber with log NHI > 19. 5) and excellent estimates for zabs and NHI.

Project AMIGA: A Minimal Covering Factor for Optically Thick Circumgalactic Gas Around the Andromeda Galaxy
Our non-detections place a limit on the covering factor of such optically-thick gas around M31 to $f_c < 0. 051$ (at 90\% confidence) for $\rho \leq R_{\rm vir}$.
