This was followed by a stay abroad between 1901 and 1903 in Paris at the Sorbonne, at the Collège de France and in Göttingen. In 1904, he became an assistant at the observatory in Uccle. In 1909, he was promoted to astronomer adjoint.

Merlin was one of the editors for the French edition of Klein's encyclopedia.
For his work on celestial mechanics, he was awarded the A. de Potter Prize of the Royal Belgian Academy of Sciences. He was president of the Belgian Mathematical Society, an honorary member of the Astronomical Society of Mexico and a member of the Commission for Mathematics and Astronomy of the National Fund for Research in Spain. He was an Invited Speaker at the International Congress of Mathematicians in Toronto 1924 (Sur les lignes asymptotiques en géométrie infinitésimale) and Oslo 1936 (Sur certains mouvements des fluid parfaits).
