Turbulent Convection: Modal Equations and Energy Pathways
S. Sridhar, Nishant K. Singh
We present a framework for studying high Rayleigh number turbulent convection to better understand stellar and planetary convection zones. Utilizing the statistical symmetries of t…
XRISM Resolves the Circum-nuclear Environment of NGC 4945
Peter G. Boorman, Poshak Gandhi, Yoshihiro Ueda +31
Compton-thick Active Galactic Nuclei (AGN) represent one of the most elusive phases of massive black hole growth, yet are expected to contribute substantially to the Cosmic X-ray B…
Impact of fiducial cosmology in model-agnostic cosmological inference with the BAO feature
Aseem Paranjape, Ravi K. Sheth
In recent work, we have developed a model-agnostic framework for cosmological inference using the baryon acoustic oscillation (BAO) feature in redshift space. The framework, which…
Resolving circumgalactic gas flows around a z3.6 quasar using MUSE and ALMA
M. Galbiati, A. Pensabene, S. Cantalupo +10
The formation and evolution of galaxies is regulated by the exchange of gas with the surrounding large-scale structures on circum- and intergalactic scales. Yet, little is known ab…
The MUSE Ultra Deep Field (MUDF) VIII. The cool gas distribution surrounding galaxies at redshifts z ~ 0.5-2
Edoardo Santo, Michele Fumagalli, Seok-Jun Chang +5
We use deep MUSE data from the MUDF survey to investigate the cool gas around galaxies at redshifts 0.5 < z < 2. We constructed two samples: one sample for a down-the-barrel analys…
Non-Trivial Zero-Knowledge Implies One-Way Functions
Suvradip Chakraborty, James Hulett, Dakshita Khurana +1
A recent breakthrough [Hirahara and Nanashima, STOC'2024] established that if , the existence of zero-knowledge with negligible errors…
A quiescent galaxy in a gas-rich cosmic web node at z~3
Weichen Wang, Sebastiano Cantalupo, Marta Galbiati +11
Recent JWST observations have unveiled a large number of quiescent galaxies at , bringing potential challenges to current galaxy formation models. Since star formation i…
Bondi-Hoyle-Lyttleton accretion onto ultra dense dark matter halos and direct collapse black holes
Kandaswamy Subramanian, Bikram Phookun
We suggest a formation scenario of black holes with intermediate mass , by post recombination Bondi-Hoyle-Lyttleton accretion into ultra dense dark matter halos…
SIEVE: Effective Filtered Vector Search with Collection of Indexes
Zhaoheng Li, Silu Huang, Wei Ding +2
Many real-world tasks such as recommending videos with the kids tag can be reduced to finding most similar vectors associated with hard predicates. This task, filtered vector searc…
Stabilizing simulation-based cosmological Fisher forecasts: a case study using the Voronoi volume function
Saee Dhawalikar, Aseem Paranjape, Shadab Alam
Forecasting cosmological constraints from halo-based statistics often suffers from instability in derivative estimates, especially when the number of simulations is limited. This i…
Scale-dependent bias and mode coupling in redshift-space clustering near the BAO scale
Aseem Paranjape, Ravi K. Sheth
The baryon acoustic oscillation (BAO) feature in the 2-point clustering of biased tracers in redshift space can be described in a model-agnostic manner, relying only on the assumpt…
The holonomy Lie -groupoid of a singular foliation I
Camille Laurent-Gengoux, Ruben Louis
We construct a finite-dimensional higher Lie groupoid integrating a singular foliation , under the mild assumption that the latter admits a geometric resolution. More…
Weak-emission-line quasars: A new clue from their optical variability
Ritish Kumar, Gopal-Krishna, Hum Chand +1
Weak-emission-line QSOs (WLQs) are an enigmatic subclass of the QSO population, as their optical/UV spectra are marked by abnormally weak (or absent) emission lines. To obtain much…
PMN J1310-5552: A Gamma-ray Emitting Blazar Candidate Harboring A Cosmic Monster
Vaidehi S. Paliya
Relativistic jets manifest some of the most intriguing activities in the nuclear regions of active galaxies. Identifying the most powerful relativistic jets permits us to probe the…
Founding Quantum Cryptography on Quantum Advantage, or, Towards Cryptography from -Hardness
Dakshita Khurana, Kabir Tomer
Recent oracle separations [Kretschmer, TQC'21, Kretschmer et. al., STOC'23] have raised the tantalizing possibility of building quantum cryptography from sources of hardness that p…
Model-agnostic basis functions for the 2-point correlation function of dark matter in linear theory
Aseem Paranjape, Ravi K. Sheth
We consider approximating the linearly evolved 2-point correlation function (2pcf) of dark matter in a cosmological model with parameters $\boldsymbol…
Information Asymmetry Index: The View of Market Analysts
Roberto Frota Decourt, Heitor Almeida, Philippe Protin +1
The purpose of the research was to build an index of informational asymmetry with market and firm proxies that reflect the analysts' perception of the level of informational asymme…
