We carry out a new analysis of the sample of MACHO microlensing candidates towards the LMC. Our main purpose is to determine the lens population to which the events may belong. We give particular emphasis to the possibility of characterising the Milky Way dark matter halo population with respect to the LMC one. Indeed, we show that only a fraction of the events have characteristics that match those expected for lenses belonging to the MACHO population of the Galactic halo. This suggests that…

Microlensing towards the Magellanic Clouds and M31: is the quest for MACHOs still open?
Microlensing is the tool of choice for the search and the analysis of compact halo objects ("MACHOs"), a still viable class of dark matter candidates at the galactic scale. Different analyses point
Large Magellanic Cloud self-lensing for OGLE-II microlensing observations
In the framework of microlensing searches towards the Large Magellanic Cloud (LMC), we discuss the results presented by the OGLE collaboration for their OGLE-II campaign (Wyrzykowski et al. 2009). We
Microlensing towards the LMC: self lensing for OGLE-II and OGLE-III
We present an analysis of the results of the OGLE-III microlensing campaign towards the Large Magellanic Cloud (LMC). We evaluate for all the possible lens populations along the line of sight the
Microlensing towards the SMC: a new analysis of OGLE and EROS results
We present a new analysis of the results of the EROS-2, OGLE-II, and OGLE-III microlensing campaigns towards the Small Magellanic Cloud (SMC). Through a statistical analysis we address the issue of
Microlensing observations toward M31 are a powerful tool for the study of the dark matter population in the form of MACHOs both in the Galaxy and the M31 halos, a still unresolved issue, as well as
Microlensing towards the LMC revisited by adopting a non-Gaussian velocity distribution for the sources
Aims. We discuss whether the Gaussian is a reasonable approximation of the velocity distribution of stellar systems that are not spherically distributed. Methods. By using a non-Gaussian velocity
Microlensing constraints on the Galactic bulge initial mass function
Aims. We seek to probe the Galactic bulge IMF starting from microlensing observations. Methods. We analyse the recent results of the microlensing campaigns carried out towards the Galactic bulge
The contribution of red dwarfs and white dwarfs to the halo dark matter
Context. The nature of the several microlensing events observed by the MACHO team towards the LMC still remains controversial. Low-mass substellar objects and stars with masses larger than ∼1 Mhave
Gravitational microlensing constraints on primordial black holes by Euclid
Primordial black holes (PBHs) may form in the early stages of the Universe via the collapse of large density perturbations. Depending on the formation mechanism, PBHs may exist and populate today the
M31 Pixel Lensing PLAN Campaign: MACHO Lensing and Self Lensing Signals
We present the final analysis of the observational campaign carried out by the PLAN (Pixel Lensing Andromeda) collaboration to detect a dark matter signal in form of MACHOs through the microlensing


Microlensing towards the Large Magellanic Cloud
The nature and the location of the lenses discovered in the microlensing surveys done so far towards the LMC remain unclear. Motivated by these questions we compute the optical depth and particularly
Are there MACHOs in the Milky Way halo
Microlensing searches aim to detect compact halo dark matter via its gravitational lensing effect on stars within the Large Magellanic Cloud. These searches have led to the claim that roughly one
The MACHO Project: Microlensing Results from 5.7 Years of Large Magellanic Cloud Observations
We report on our search for microlensing toward the Large Magellanic Cloud (LMC). Analysis of 5.7 yr of photometry on 11.9 million stars in the LMC reveals 13-17 microlensing events. A detailed
Direct detection of a microlens in the Milky Way
A direct image of a microlens is reported, revealing it to be a nearby low-mass star in the disk of the Milky Way, and demonstrates a direct determination of a lens mass from amicrolensing event.
POINT-AGAPE pixel lensing survey of M31: Evidence for a MACHO contribution to galactic halos
The POINT-AGAPE collaboration is carrying out a search for gravitational microlensing toward M31 to reveal galactic dark matter in the form of MACHOs (Massive Astrophysical Compact Halo Objects) in
The Stellar Halo in the Large Magellanic Cloud: Mass, Luminosity, and Microlensing Predictions
Recently obtained kinematic data have shown that the Large Magellanic Cloud (LMC) possesses an old stellar halo. In order to further characterize the properties of this halo, parametric King models

Self-Lensing Models of the LMC
All of the proposed explanations for the microlensing events observed towards the LMC have difficulties. One of these proposed explanations, LMC self-lensing, which invokes ordinary LMC stars as the
Probing the large magellanic cloud halo for machos
If galactic halos are composed of massive compact halo objects (MACHOs) in the mass range M≤0.01 M ○ ., then ongoing gravitational lensing experiments could be capable of detecting them in the Large
LMC self-lensing from a new perspective
We present a new analysis of the location of the observed microlensing events in the direction of the Large Magellanic Cloud (LMC). This is carried out starting from a recently drawn coherent picture
