The Astrophysical JournalWe used the FourStar near-IR camera on Magellan–Baade to obtain high signal-to-noise ratio H -band imaging of 66 galaxies with radial velocities of 2000 km s ^–1 ≤ V ≤ 5000 km s ^−1 .

Clustering and redshift-space distortions in QSO and galaxy surveys [PDF]
, 2006 In this thesis, we exploit the potential of existing QSO and galaxy surveys for investigating the nature of the large scale structure in the Universe. A detailed analysis of clustering and redshift- space distortions allows us to constrain cosmological ...

The Anatomical Record, EarlyView.Abstract The oval window (OW) is an opening connecting the inner and middle ear. Its area has been shown to consistently scale with body mass (BM) in primates, and has been used alongside semi‐circular canal (SCC) size to differentiate Homo sapiens and fossil hominins, including Paranthropus robustus.

Cosmology with Topological Deep Learning
The Astrophysical JournalThe standard cosmological model with cold dark matter posits a hierarchical formation of structures. We introduce topological neural networks (TNNs), implemented as message-passing neural networks on higher-order structures, to effectively capture the ...

Forward Modeling of Galaxy Populations for Cosmological Redshift Distribution Inference
The Astrophysical Journal Supplement Series, 2023 We present a forward-modeling framework for estimating galaxy redshift distributions from photometric surveys. Our forward model is composed of: a detailed population model describing the intrinsic distribution of the physical characteristics of galaxies,

Direct SMBH Formation Driven by Runaway Stellar Collisions in Globally Unstable Stellar Systems
Astronomische Nachrichten, EarlyView.ABSTRACT The fueling problem addresses the ultimate fate of the reservoirs of gas and stars driven into the deepest gravitational potential wells of galaxies, thus it may contain the Universe's densest concentrations of gas and stars. This raises a key question: does the infalling material collapse directly into a supermassive black hole, or can it ...

Journal of Quaternary Science, EarlyView.ABSTRACT The Cadí Massif (42°17′09″ N, 1°38′11″ E; 2649 m a.s.l.) in the southeastern Pyrenees preserves clear evidence of Late Pleistocene glaciation, although previous research has focused almost exclusively on its northern slope. By contrast, the southern slope has remained largely unexplored.

The Astrophysical JournalWe present a study on the inference of cosmological and astrophysical parameters using stacked galaxy cluster profiles. Utilizing the CAMELS-zoomGZ simulations, we explore how various cluster properties—such as X-ray surface brightness, gas density ...

Cosmological parameters from complementary observations of the Universe
, 2001 We use observational data on the large scale structure (LSS) of the Universe measured over a wide range of scales from sub-galactic up to horizon scale and on the cosmic microwave background anisotropies to determine cosmological parameters within the ...
