We propose a novel method of extracting the imprint of gravitational lensing by Population III stars in the light curves of gamma-ray bursts (GRBs). Significant portions of GRBs can originate in hypernovae of Population III stars and be gravitationally lensed by foreground Population III stars or their remnants. If the lens mass is on the order of 102-103 M☉ and the lens redshift is greater than 10, the time delay between two lensed images of a GRB is ≈1 s and the image separation is ≈10 μas… 
Imprints of Gravitational Microlensing on the Light Curve of Gamma-Ray Bursts
In this work, we search for signatures of gravitational microlensing in Gamma-ray bursts (GRB) in which the source-lens-observer geometry produces two images that manifest in the GRB light curve as
Imprints of Gravitational Millilensing on the Light Curve of Gamma-Ray Bursts
In this work, we search for signatures of gravitational millilensing in gamma-ray bursts (GRBs) in which the source−lens−observer geometry produces two images that manifest in the GRB light curve as
Strong lensing of gamma ray bursts as a probe of compact dark matter
Compact dark matter has been efficiently constrained in the M ~ 10 M_sun by seeking echoes in gamma-ray-burst light curves induced by strong lensing. We show that strong gravitational lensing of
Evidence for an intermediate-mass black hole from a gravitationally lensed gamma-ray burst
If gamma-ray bursts are at cosmological distances, they must be gravitationally lensed occasionally [1, 2]. The detection of lensed images with millisecond-to-second time delays provides evidence for
Fermi-GBM Observation of GRB 090717034: χ 2 Test Confirms Evidence of Gravitational Lensing by a Supermassive Black Hole with a Million Solar Mass
Gravitational lensing of gamma-ray bursts (GRBs) can provide an opportunity to probe the massive compact objects in the universe at different redshifts. We have discovered two consecutive pulses in
The prospects and strategies for detecting afterglows of gamma-ray bursts from population Ill stars
This thesis addresses one of the most significant challenges in modern astronomy: the detection of the first stars in the Universe. These stars, known as Population III (Pop III) stars, are expected

A Search for Gravitationally Lensed Gamma-Ray Bursts in the Data of the Interplanetary Network and Konus-Wind
We examine a sample of 2301 gamma-ray bursts, detected by Konus-Wind in the triggered mode between 1994 and 2017 and localized by the interplanetary network (IPN), for evidence of gravitational
A Search for Millilensing Gamma-Ray Bursts in the Observations of Fermi GBM
Millilensing of gamma-ray bursts (GRBs) is expected to manifest as multiple emission episodes in a single triggered GRB with similar light-curve patterns and similar spectrum properties. Identifying
Search for Lensing Signatures from the Latest Fast Radio Burst Observations and Constraints on the Abundance of Primordial Black Holes
The possibility that primordial black holes (PBHs) form some part of dark matter has been considered for a long time but poorly constrained over a wide mass range. Fast radio bursts (FRBs) are bright

Microlensing of Gamma-Ray Bursts by Stars and MACHOs
The microlensing interpretation of the optical afterglow of GRB 000301C seems naively surprising, since a simple estimate of the stellar microlensing rate gives less than one in 400 for a flat ΩΛ =
Microlensing of Gamma-Ray Burst Afterglows
The afterglow of a cosmological gamma-ray burst (GRB) should appear on the sky as a narrow emission ring of radius ~3 × 1016 cm (t/day)5/8 that expands faster than light. After a day, the ring radius
On the probability of microlensing in gamma-ray burst afterglows
The declining light curve of the optical afterglow of gamma-ray burst (GRB) GRB000301C showed rapid variability with one particularly bright feature at about t−t0=3.8 d. This event was interpreted as
Distortion of gamma-ray burst light curves by gravitational microlensing
TLDR
It is shown that microlensing by individual stars in the lensing galaxy can smear out the light curves of the multiply imaged bursts on millisecond time-scales, resulting in the appearance of two very similar bursts from the same location with a relative time delay of hours to a year.
Gamma-ray bursters at cosmological distances
It is proposed that some, perhaps most, gamma-ray bursters are at cosmological distances, like quasars, with a redshift of about 1 or 2. This proposition requires a release of supernova-like energy

Gamma-Ray Bursts as a Probe of the Very High Redshift Universe
There is increasingly strong evidence that gamma-ray bursts (GRBs) are associated with star-forming galaxies and occur near or in the star-forming regions of these galaxies. These associations
Cosmological Microlensing Statistics: Variability Rates for Quasars and Gamma-Ray Burst Afterglows and Implications for Macrolensing Magnification Bias and Flux Ratios
The fraction of quasars and gamma-ray burst (GRB) afterglows that vary because of microlensing by the stellar populations of intervening elliptical/S0 galaxies is computed by combining the joint
Redshifts and Luminosities for 112 Gamma-Ray Bursts
Two different luminosity indicators have recently been proposed for gamma-ray bursts that use gamma-ray observations alone. They relate the burst luminosity (L) with the time lag between peaks in

We present a complete sample of 29 gamma-ray bursts (GRBs) for which it has been possible to determine temporal breaks (or limits) from their afterglow light curves. We interpret these breaks within
