# VVV Survey Microlensing: Catalog of Best and Forsaken Events

## TL;DR

This paper presents a catalog of 630 microlensing events detected in the Galactic Bulge using near-infrared data from the VVV Survey, analyzing their properties, extinction effects, and special event types.

## Contribution

It provides the first comprehensive near-IR microlensing event catalog in the Galactic Bulge, including detailed parameters and analysis of event characteristics and extinction.

## Key findings

- Mean timescale decreases near the Galactic minor axis.
- 290 events have red-clump sources for extinction analysis.
- Examples include binaries, short timescale, and parallax events.

## Abstract

We search for microlensing events in the zero-latitude area of the Galactic Bulge using the VVV Survey near-IR data. We have discovered a total sample of $N=630$ events within an area covering $20.68 deg^2$ between the years 2010 and 2015. In this paper we describe the search and present the data for the final sample, including near-IR magnitudes, colors and proper motions, as well as the standard microlensing parameters. We use the near-IR Color-Magnitude and Color-Color Diagram to select $N_{RC}=290$ events with red-clump sources to analyze the extinction properties of the sample in the central region of the Galactic plane. The timescale distribution and its dependence in the longitude axis is presented. The mean timescale decreases as we approach the Galactic minor axis ($b=0$ deg). Finally, we give examples of special microlensing events, such as binaries, short timescale events, and events with strong parallax effect.
