Testing the Standard Cosmological Model [PDF]

open access: yes, 2011
This thesis exploits the wealth of information contained in the existing cosmological surveys, and demonstrates how the use of tools such as two-point statistics permit the extraction of such information.

Does the Correlation between 2MRS Galaxies and the CMB Indicate an Unmodeled CMB Foreground?

open access: yesThe Astrophysical Journal
We revisit the claimed detection of a new cosmic microwave background (CMB) foreground based on the correlation between low-redshift Two Micron All Sky Survey Redshift Survey (2MRS) galaxies and CMB temperature maps from the Planck and Wilkinson ...

Patchy Kinetic Sunyaev–Zel’dovich Effect with Controlled Reionization History and Morphology

open access: yesThe Astrophysical Journal, 2023
Using the novel semi-numerical code for reionization AMBER, we model the patchy kinetic Sunyaev–Zel’dovich (kSZ) effect by directly specifying the reionization history with the redshift midpoint z _mid , duration Δ _z , and asymmetry A _z .

Toward Large Nonradiating Qubits: When Quantum Engineering Meets Photonics

open access: yesAdvanced Quantum Technologies, Volume 9, Issue 3, March 2026.
Nonradiating superconducting qubits suppress radiative losses through photonic‐inspired mechanisms such as anapole states and bound states in the continuum (BICs). This review surveys theoretical foundations and recent implementations of large, wavelength‐scale qubits that confine electromagnetic energy while maintaining coherence.

Electrons in the cosmic radiation [PDF]

open access: yes, 1990
The nature of cosmic ray electrons and their radiation in the Universe has been studied. A convection associated diffusion model is proposed to describe the main characteristics of the large-scale distribution of cosmic ray electrons in the Galaxy: (1) a

CMB (Cosmic Microwave Background)

open access: yes, 2023
This thesis, titled CMB (Cosmic Microwave Background), is a 15-minute musical work for a chamber sextet with live electronics and interactive video. It is a quasi-spectral work that utilizes sonifications and data from the Cosmic Microwave Background ...

Revisiting the A L Lensing Anomaly in Planck 2018 Temperature Data

open access: yesThe Astrophysical Journal
We revisit the lensing anomaly in the Planck 2018 temperature (TT) data and examine its robustness to frequency selection and additional sky masking. Our main findings are as follows.

The cosmic microwave background radiation temperature at a redshift of 2.34 [PDF]

open access: yesNature, 2000
The existence of the cosmic microwave background radiation is a fundamental prediction of hot Big Bang cosmology, and its temperature should increase with increasing redshift. At the present time (redshift z = 0), the temperature has been determined with high precision to be T(CMBR)(0) = 2.726 +/- 0.010 K.
