Remembering George Smoot
John Berliner, Tom Broadhurst, Martin Bucher +31
George Smoot (1945-2025) was a major figure in observational cosmology, particularly through his role in the precision measurement of the CMB dipole and the discovery of the primor…
Infalling ultra-faint dwarfs as emissaries of the Axiverse
A. Pozo, T. Broadhurst, H. N. Luu +8
Recent discoveries of ultra-faint dwarf galaxies (UFDs) infalling onto the Milky Way, namely Leo K \& M at kpc, considerably strengthens the case that UFDs constitute…
Model Independent Dark Matter Properties from Cosmic Growth
Tilek Zhumabek, Mikhail Denissenya, Eric V. Linder
Dark matter dominates the matter budget of the universe but its nature is unknown. Deviations from the standard model, where dark matter clusters with the same gravitational streng…
Galaxy formation with wave/fuzzy dark matter: The core-halo structure and the solitonic imprint
Alvaro Pozo, Razieh Emami, Philip Mocz +9
Dark matter-dominated cores have long been claimed for the well-studied local group dwarf galaxies. More recently, extended stellar halos have been uncovered around several of thes…
Connecting Primordial Gravitational Waves and Dark Energy
Tilek Zhumabek, Mikhail Denissenya, Eric V. Linder
Cosmic acceleration manifested in the early universe as inflation, generating primordial gravitational waves detectable in the cosmic microwave background (CMB) radiation. Cosmic a…
Testing Cosmology with Double Source Lensing
Divij Sharma, Thomas E. Collett, Eric V. Linder
Double source lensing provides a dimensionless ratio of distance ratios, a "remote viewing" of cosmology through distances relative to the gravitational lens, beyond the observer.…
Using Host Galaxy Photometric Redshifts to Improve Cosmological Constraints with Type Ia Supernova in the LSST Era
Ayan Mitra, Richard Kessler, Surhud More +2
We perform a rigorous cosmology analysis on simulated type Ia supernovae (SN~Ia) and evaluate the improvement from including photometric host-galaxy redshifts compared to using onl…
Constraining Scale Dependent Growth with Redshift Surveys
Mikhail Denissenya, Eric V. Linder
Ongoing and future redshift surveys have the capability to measure the growth rate of large scale structure at the percent level over a broad range of redshifts, tightly constraini…
Double Source Lensing Probing High Redshift Cosmology
Divij Sharma, Eric V. Linder
Double source lensing, with two sources lensed by the same foreground galaxy, involves the distance between each source and the lens and hence is a probe of the universe away from…
Understanding the "Feeble Giant" Crater II with tidally stretched Wave Dark Matter
A. Pozo, T. Broadhurst, R. Emami +1
The unusually large "dwarf" galaxy Crater II, with its small velocity dispersion, km/s, defies expectations that low mass galaxies should be small and dense. We combine…
A novel approach for calculating galaxy rotation curves using spaxel cross-correlation and iterative smoothing
Satadru Bag, Arman Shafieloo, Rory Smith +5
Precise measurements of the internal dynamics of galaxies have proven of great importance for understanding the internal dark matter distribution of galaxies. We present a novel me…
Finding quadruply imaged quasars with machine learning. I. Methods
A. Akhazhanov, A. More, A. Amini +68
Strongly lensed quadruply imaged quasars (quads) are extraordinary objects. They are very rare in the sky -- only a few tens are known to date -- and yet they provide unique inform…
Out of One, Many: Distinguishing Time Delays from Lensed Supernovae
Mikhail Denissenya, Satadru Bag, Alex G. Kim +2
Gravitationally lensed Type Ia supernovae are an emerging probe with great potential for constraining dark energy, spatial curvature, and the Hubble constant. The multiple images a…
Inflation Story: slow-roll and beyond
Dhiraj Kumar Hazra, Daniela Paoletti, Ivan Debono +3
We present constraints on inflationary dynamics and features in the primordial power spectrum of scalar perturbations using the Cosmic Microwave Background temperature, polarizatio…
Testing generalized logotropic models with cosmic growth
Kuantay Boshkayev, Talgar Konysbayev, Orlando Luongo +2
We check the dynamical and observational features of four typologies of logotropic dark energy models, leading to a \emph{thermodynamic cosmic speed up} fueled by a single fluid th…
Partially Constrained Internal Linear Combination: a method for low-noise CMB foreground mitigation
Y. Sultan Abylkairov, Omar Darwish, J. Colin Hill +1
Internal Linear Combination (ILC) methods are some of the most widely used multi-frequency cleaning techniques employed in CMB data analysis. These methods reduce foregrounds by mi…
Tracing dark energy history with gamma ray bursts
M. Muccino, L. Izzo, O. Luongo +5
Observations of gamma-ray bursts up to are best suited to study the possible evolution of the Universe equation of state at intermediate redshifts. We apply the Combo-rel…
A paradigm of warm quintessential inflation and production of relic gravity waves
Mayukh R. Gangopadhyay, Shynaray Myrzakul, Mohammad Sami +1
We consider the framework of quintessential inflation in the warm background which is caused by the dissipation of the scalar field energy density into relativistic degrees of free…
Cosmology Requirements on Supernova Photometric Redshift Systematics for Rubin LSST and Roman Space Telescope
Ayan Mitra, Eric V. Linder
Some million Type Ia supernovae (SN) will be discovered and monitored during upcoming wide area time domain surveys such as the Vera C. Rubin Observatory Legacy Survey of Space and…
Fast Radio Burst Dispersion Measure Distribution as a Probe of Helium Reionization
Mukul Bhattacharya, Pawan Kumar, Eric V. Linder
Fast radio burst (FRB) discoveries are occurring rapidly, with thousands expected from upcoming surveys. The dispersion measures (DM) observed for FRB include important information…

The Well-Tempered Cosmological Constant: Fugue in B
Stephen Appleby, Eric V. Linder
Zero point fluctuations of quantum fields should generate a large cosmological constant energy density in any spacetime. How then can we have anything other than de Sitter space wi…
The Well-Tempered Cosmological Constant: The Horndeski Variations
Stephen Appleby, Eric V. Linder
Well tempering is one of the few classical field theory methods for solving the original cosmological constant problem, dynamically canceling a large (possibly Planck scale) vacuum…
