A semi-analytic afterglow with thermal electrons and synchrotron self-Compton emission
Donald C. Warren, Maria Dainotti, Maxim V. Barkov +3
We extend previous work on gamma-ray burst (GRB) afterglows involving hot thermal electrons at the base of a shock-accelerated tail. Using a physically-motivated electron distribut…
Gamma-ray burst data strongly favor the three-parameter fundamental plane (Dainotti) correlation relation over the two-parameter one
Shulei Cao, Maria Dainotti, Bharat Ratra
Gamma-ray bursts (GRBs), observed to redshift , are potential probes of the largely unexplored part of the early Universe. Thus, finding relevant relations a…
Interpretation of Radio Afterglows in the framework of the Standard Fireball and Energy Injection models
Delina Levine, Maria Dainotti, Nissim Fraija +3
Gamma-Ray Bursts (GRBs) are panchromatic, highly energetic transients whose energy emission mechanism is still debated. One of the possible explanations is the standard fireball mo…
An Intertwined Short and Long GRB with 4-minute Separation
Liang Li, Yu Wang, Bing Zhang +19
Gamma-ray bursts (GRBs), the most energetic transients in the Universe, are traditionally classified into long-duration ( s) and short-duration ( s) events, ass…
Variation of Microphysical Parameters in Reverse-shock Scenario
Nissim Fraija, Boris Betancourt-Kamenetskaia, Antonio Galván +1
Gamma-ray bursts (GRBs), among the most compelling astrophysical phenomena, are potential candidates for exploring the evolution of energy distribution among magnetic fields and pa…
Gamma Ray Burst afterglow and prompt-afterglow relations: an overview
Maria Dainotti, Roberta Del Vecchio
The mechanism responsible for the afterglow emission of Gamma Ray Bursts (GRBs) and its connection to the prompt -ray emission is still a debated issue. Relations between intri…
Cosmology Intertwined: A Review of the Particle Physics, Astrophysics, and Cosmology Associated with the Cosmological Tensions and Anomalies
Elcio Abdalla, Guillermo Franco Abellán, Amin Aboubrahim +200
In this paper we will list a few important goals that need to be addressed in the next decade, also taking into account the current discordances between the different cosmological…
Examining Two-Dimensional Luminosity-time Correlations for Gamma Ray Burst Radio Afterglows with VLA and ALMA
Delina Levine, Maria Dainotti, Kevin J. Zvonarek +4
Gamma-ray burst (GRB) afterglow emission can be observed from sub-TeV to radio wavelengths, though only 6.6\% of observed GRBs present radio afterglows. We examine GRB radio light…
Radio-bright vs. Radio-dark Gamma-ray Bursts -- More Evidence for Distinct Progenitors
Angana Chakraborty, Maria Dainotti, Olivia Cantrell +1
We analyze two distinct samples of GRBs, with and without radio afterglow emission. We use a sample of 211 GRBs which is an update of the previous sample from arXiv:1902.01974, and…
A Comparison between Radio Loud and Quiet Gamma-Ray Bursts, and Evidence for a Potential Correlation between Intrinsic Duration and Redshift in the Radio Loud Population
Nicole M. Lloyd-Ronning, Ben Gompertz, Asaf Pe'er +2
We extend our study of energetic radio loud and quiet gamma-ray bursts (GRBs), suggesting these GRBs potentially come from two separate progenitor systems. We expand the sample fro…
Gamma Ray Burst Prompt correlations
Maria Dainotti, Roberta Del Vecchio, Mariusz Tarnopolski
The mechanism responsible for the prompt emission of gamma-ray bursts (GRBs) is still a debated issue. The prompt phase-related GRB correlations can allow to discriminate among the…
Gamma-ray Bursts as distance indicators through a machine learning approach
Maria Dainotti, Vahé Petrosian, Malgorzata Bogdan +7
Gamma-ray bursts (GRBs) are spectacularly energetic events, with the potential to inform on the early universe and its evolution, once their redshifts are known. Unfortunately, det…
Spectral and Polarization Properties of Photospheric Emission From Stratified Jets
Hirotaka Ito, Shigehiro Nagataki, Jin Matsumoto +5
We explore the spectral and polarization properties of photospheric emissions from stratified jets in which multiple components, separated by a sharp velocity shear regions, are di…
GRB Redshift Estimation using Machine Learning and the Associated Web-App
Aditya Narendra, Maria Dainotti, Milind Sarkar +7
Context. Gamma-ray bursts (GRBs), observed at redshifts as high as 9.4, could serve as valuable probes for investigating the distant Universe. However, this necessitates an increas…
A Study of the Gamma-Ray Burst Fundamental Plane
Maria Dainotti, Christian Gilbertson, Sergey Postnikov +2
A class of long gamma-ray bursts (GRBs) with a plateau phase in their X-ray afterglows obeys a three-dimensional (3D) relation (Dainotti et al. 2016), between the rest-frame time a…
Standardizing Platinum Dainotti-correlated gamma-ray bursts, and using them with standardized Amati-correlated gamma-ray bursts to constrain cosmological model parameters

We show that the Platinum gamma-ray burst (GRB) data compilation, probing the redshift range , obeys a cosmological-model-independent three-parameter fundame…
Accounting for Selection Bias and Redshift Evolution in GRB Radio Afterglow Data
Maria Dainotti, Delina Levine, Nissim Fraija +1
